I'm working on an animation background which involves a high angle shot of a forest. I searched on internet to hunt some references for the trees and other foliage from such an angle. I could only find real photos or fully rendered paintings and what I drew from those didn't seem right. So I went to my faculty for support, he asked me to keep hunting for references. Now after growing tired of looking through the same images I've come here to seek help. I'm looking for a link to a webpage that will have a tutorial for it or even a reference image of a drawing.
