I'm gonna have to fix that chin later.
I hear you should usually wait a while after finishing something before you declare it "finished." It's because of this kind of blindness. Sometimes, when you work on something for a while, you can start to miss things that would normally be obvious. Put it down for a few hours (or until the next day) and suddenly all the flaws jump out at you.
Of course, it's just a practice picture, so I'm not going to get too worked up about it, but things are really jumping out at me now.
Can you spot the venomous snake in this photo?
