the cart next to the market looks like its floating
It does ? ummm
try making the buildings longer, the carts as long as the entire building, that might help
The buildings look a little thing, the cart is half as long as the buildings. The far building looks like it's being overlapped by sky aswell. Although, I like the style, very clean and has potential. Good luck with it. :)
EDIT: Damn, LostTraveler beat me to it. :P
ya maybe all move it to the front and it would look better .
Thanks for the help .
