I love Peter and Wendy, because they seem so much younger tan the other characters but not so much that they look out of place. Plus the pose gives Peter that still childlike aura that is absolutely necessary to Peter.
Disney Princess Poster by suisei-ojii-sama on deviantART. Btw, the tribal princess is Nala from The Lion King. However, I do not know who the one in the bottom left hand corner is. Also, why are there 3 Ariels?
More Disney princesses from DeviantArt. There are some evil characters too :) These ones are Esmeralda, Jasmine, Meg, Rapunzel, Snow White and Pocahontas. What I like about these it these drawings don't makes the princesses look like sticks.
