I don't know, it's late. I mean it still looks like him so it hasn't been pushed too far I guess. But it's kind of lost the humour a little. His lips are big but they aren't that thick. It's kind of starting to remind me of that singing creature in return of the jedi.
I don't think I'll pursue this any further. I may paint one of the other ones or I might switch reference tomorrow. My iPod just died so that's it for sketching tonight. Still, tomorrow's another day right?
