Since I am really stuck I thought of asking for help or rather comments and crits on what I could do next.

as you can see it's rather smudgy.

Any suggestions or anything?
and can you see what character this is?

there are some problems with anatomy and lighting in this one...if you have a ref for this one then take a really good look at it and try to find out what's wrong. I do suggest that you study some anatomy though, sometimes a step back can make you take multiple forward...it's hard work but it pays off.
Good luck!

What I should have done is drawn rough guidelines. might have helped me more.

I think you need to determine a light source..

i thought i would tell you some specific things that bothered me. first, i noticed that the facial structure wasn't actually too bad. the right eye seems a little droopy and the depression in the lip is way too wide though. the shading is where the problems seem to lie. you seem to have at least a reasonably good idea of where to place shadows, and the skintones for the stubble look good to me. but his whole face has kind of a plasticy feeling.
