I came across this painting tutorial from Denise Thewissen while blog hopping last week and just had to try it out. You draw a simple picture-I did a silhouette of a bird on a branch (me, birds, go figure...), then draw several geometric shapes over that, overlapping wherever you want and letting some run off the edges of your piece. After that begin filling in with color, not letting the same color touch and trying to alternate warm and cold colors. Here's my finished painting:
I feel like I want to go back and shade it...or something...?? Anyway--it was a lot of fun to do.
