This is what I've come up with to add to my "Barn Scene".   I'm sort of a perfectionist, and those dang leaves are giving me fits.  I know I can't draw every single leaf, but I want to.  So, I have to be able to do something that will represent the foliage and something that I'll be happy with.  Now, all I have to do is draw it onto the other sketch (of the barn)... easier said than done.
