Painting Photorealistic Leaves?
This is as close as I've been able to get so far. How do I make this mass look like it's made of leaves? It's supposed to be a bush or tree. I'm pretty new to painting in PS and can't figure out how to do textures like leaves. I also tried drawing each leaf individually, but it looked bad and I deleted the layer. Doing it that way would have taken a really long time, too.

Any help appreciated.
