I had a painting about halfway done, and have realized it's just Not Working.
Which sucks, because the idea is horrible and wonderful, and I really, really want to do a painting of it, but...this one didn't work. The sketch was good, but the composition failed as a painting. It just doesn't hang together.
I hate that.
So it'll go back to the mental slush pile, and hopefully I'll figure out some way to do it at some point.
