I can't help but notice you have 6 threads, 5 of which newly posted in row. Was this entirely neccessary?

(your first three images don't work, either)

Maybe you have a problem with your connection, because all the pictures i posted works well... i didn't want to post all in the same topics, because i wanted all separate by subjects.

I can't really critique them all (all of your posts) but I really like them!
Especially these!
But perhaps you could try to vary the lineweight a little to better communicate shapes and perspective?!

Yes Sukhoi, you're right, but at the base, i did this simple lineart for been after paint under photoshop, and the line will diseapear, but you true, a varriations of line space and maybe a use of a grey marker for shadows would be better
