I do like paintings that are rather dark sometimes, for their moodiness and drama. But somehow in my studio the shadow side didn't seem quite so dark. I know when you look at dark areas for a long time the iris of your eye will open wider, letting more light in. This will allow you to see things better even when it's dark. I think that may have been what was happening here. In an effort to create a strong shadow I think my peepers were fooling me. That's why the shadow side looks a bit extreme to me now and he kind of looks like he has a black eye.
Anyway, another lesson learned. There are still things I like here. The handling of the mouth, and a couple of other things, so not a total failure.

Also, I think if I were going to do this painting over I would probably do a horizontal crop, something like this.
I think this works better. Hey, photoshop does a lot, but it can't cut my panel down so it fits in a frame. ;-)
