Sprites: Lilo and Stitch - Lilo and Stitch - Pokemon VS. Sprites

I've now done Lilo and Stitch. Lilo was decently easy, but Stitch was very hard. I tried my best to capture his cheeky smile, and I think I sorta did it. Sorry if Stitch looks a bit retarded, but please conside the fact that his face isn't like a human one, and plus the fact it's on an angle, it doesn't help. So please forgive the fact Stitch looks very retarded. Though overall, I say I did a good job. Any suggestions for the next one? I'm thinking Buzz and Woody from Toy Story (if you leave any suggestions, please make sure it's a duo)
