PLAN AHEAD! I was playing around with a 9 x 12 piece of hard board and wanted to practice clouds, trees, etc. I made my tree too big and there wasn't enough room to do the whole tree! ha! I practiced a little more with highlights and I see where I can enhance those on the tree trunk a little more now but thought I'd share anyway.
p.s. NOT liking clouds the way I tried them. I think I'll head to the University of Youtube to learn other techniques :)
