Playing with some different ways to get it done.

The first is a 3D model with some front projection textures of a Painter watercolor texture. I started with a gray color and adjusted that to get all the other colors. I also used an AmbientOcclusion plugin.




Some work on my regular art after poking thru my Color Drawing book.
Felt Marker - leaves
Flat Color Pen - outlines
Cover Pencil - highlights, texturing
just a little Basic Round Tinting.




I'll eventually have the same scene rendered as
- Photo real 3D (as best as I can)
- Water color over 3D, like the first image.
- Hand painted (probably a paint-over so I have every model the way I want before I start)

Update of my 3D work.
I have a job for a house render so that will get done 2 ways.
This is just a test area.
3D hedge and ground leaves I like the way the leaves work on the grass. I'll probably add more around the hedges.

2D trees
I'll be buying some more cars and trees like shown here and buying some 3D people.

no radiosity, I set up 8 distance lights covering the compass directions set to light blue. 1 area light sun light yellow/orange. AmbientOcclusion on most things to get the shadows I didnt get from radiosity.

This is the current project.

Its an addition on an existing house.
New stuff:
Garage with bedrooms
kitchen window bump out
porch at front door
35x25 family room at rear, cant see it

Most of the existing house is getting work done. The second floor will have 6 bedrooms and each will have its own bathroom Smile The estimate for the work here is 900k. So the architect figured he would pay for a render since its a massive payday for him.

Still more to go, I want to add some plants and leaves on the ground.
I enlarged the grass texture from 1m to 2 m, so there is more texture to it. Just too tight at 1m.
I also dropped the saturation and increased the spec on the bushes.

I am not certain about some of the shadows..some of the shadows seem to be either too big, too dark or in the wrong direction but it is not obviously so...just a quick impression
Overall..the work is very nice..I have looked at many photos of houses and this is so much clearer and cleaner. The perspective is sharp..and very impressive
Nice Job ..and the shadows are probably fine as is Smile

Some minor considerations:
The window frames...In a photograph..a person should be able to measure the proportional dimensions of the building to determine the dimensions of the building.
The historical homes that were buried under Lake Marion in St. John's Parish, Berkeley County, South Carolina were photographed in the 1930's before being unindated. By studying the rough drawings of the floor dimensions and using proportional measuring of arrchitectural elements in the surviving photos, the actual dimensions of all architectural elements can be determined.
That means that small architectural details are very important such as the accurate dimensions and placement of window panes which are standard in most era's..as that can give clues to the height of the ceiling or the dimensions of a room
The window pane placement and arrangment in your drawing is not clear..
The question to ask is "If only your drawing survived as the sole plan for that house, could the house be historically and accurately recreated from that representation?"
The fragment of information surviving about historical residents, including Pond Bluff, Francis Marions home, is an intriguing study in rendering and measuring and determining which are the most significant elements of a rendition..
Create a good record just in case..and maybe take a look at the surviving data of St. John's Parish..and see if you can determine the actual measurements of the architectural elements..intriguing bit of detective work and very educational Smile

Shadows
I was thinking about altering the garage where the doors are to make it darker. But so far have decided not to do it. Everything is lit the same way, I think the grass looks darker in shadow because the grass base color is just darker than the house. If I dropped the lighting facing the doors it would effect the grass too.


Window panes
The image above has wobbly grill lines because of the low rez render. In the Finished forum I have a higher rez version.

Also All the windows are made by Andesen and I have the catalog which includes head/jamb/sill details so the windows are acurate to within 1/4", you have to draw the line somewhere Smile Glass panes aren't really panes anymore. The grills are plastic that snap into place and come in all sizes and proportions.

Long ago things did come in just a few sizes so it would be easy to extrapolate a house from it. Well easier Smile

--------

When I have a job to put an addition on a house I take a picture of the existing. I also measure the clapboard size. When I get home I can count clapboards to figure out how high the peak of the roof is.

The big shadows across the lawn don't seem to have a source..but that is just a quick glance and the darkness probably is the underlying grass color..I prefer things lighter but realism dictates in this case..It is fine the way it is
That attention to detail with the siding probably makes more sense than window panes because glass comes from so many different sources and can be custom made nowadays..Siding is standard and not too many widths available..where window glass used to be in a few sizes only..Just one small detail done correctly can give all the information historical restorers need but it has to be the right detail...
The panes are much clearer now..not so wavy or so many different numbers..as when I first looked
Thanks for clearing it up about the rez..and considering the other uses that the pictures might have in the future Smile

The source for the big shadows are trees that are out of frame to the right. There are 3 in the center of the circular drive area and a few more on the camera side of the driveway. The lot has about 30 trees in the front yard.

So when the customer sees this it will make sense to them because they know about all the trees.

I didnt want to put one of those 2D tree images in the foreground.

The fact of other trees just out of sight makes perfect sense and would increase the overall impression of shady. The lot really is that shaded..Good Job
That attention to detail is important now and maybe in the future..to other owners or restorers..who may wonder if that old stump in the front yard was a big tree when the house was built
Very nice job!
