the beauty about working in oils is that if you don't like something, paint over it. i guess that you can do that w/acrylics, too, but i really like it in oil because of the weight that it'll give as you go over what you didn't like.
in this piece, i originally had a bunch of swirls. you can still see them in the photo, although they're covered. they start @ the bottom left and move up through the center. i was planning on just a light cover over them, and as i first started i thought it looked alright. the more i did, the less i liked. but i also got paint coverage over everything and color wise this is definitely where i'm headed on the piece. of course, i've got something i'm going to try on it as i continue to layer over the swirls, we'll see how i like that.
