Hey Albert, if you want to use those circle shapes, make sure you repeat them in the distance. So it defies the depth of the whole picture. I like the fact that you spread the buildings out. But they look like they are built on top of jelly. Make sure they are built on solid rock, tilted top house is little too much. I'll stop by tomorrow or Tuesday to give you a book you can use. I want you to scan the entire book so you can use it. Talk to you soon. Thanks.
