I wanted a Lombardy Poplar for the Atlantas Challenge. The tree lab makes good trees if the aspect of height to width is about 1. Anything else and you start having bare trunks. Tall trees and oblong would be good. Trees like Baobab and Cypress where the trunk texture is important or they have extras like knees. Interesting or twisted trees, graveyard oak, trees topped by lightning, Poohs hollow honey tree, Bonsaii. Lo and Hi Res plants so you could do a field scene. A detailed daisy with 1000 polys for the foreground and one with 64 to pose in the background. Thanks!
