I need to do a little research and see if i really should be calling these "abstract expressionist?" All i know is not much thought is put into design or colors when they're started. I just stop when i like them. I like the yellow square at the bottom of this one. It's a total accident. It wasn't planned. But maybe as the Freud saying goes "there are no accidents." I do think about balance though and try to make sure the eye doesn't get stuck in one place, or if all the action is on one side to balance with something on the other side.
