FWIW, I don't think a messy finish is necessarily a bad thing. Cartoony styles like what you're doing now can work quite well with it. Also, I love your outrageously neon color pallete. One thing that bothers me is that is seems like you are moving away from your own style with the flamingo. Its proportions aren't deformed like the frog's and the giraffe's, and it's making the style look inconsistent. Also the shade of pink you chose isn't burning my eyes enough, make it hotter.
Edit: One more thing: I think it would totally look cooler if the flamingo was holding his knife with its raised foot.
hmm on my screen the pink looks relatively the same in it's..uh...neonness.. xD haha. I'll try adjusting the saturation on my next update. As for the flamingo itself..well it's a bird..and most birds in general don't really get fat..let alone flamingos LOL .i wasnt going to give it a beer gut and belly button which is really what is making the other two seem so similar i guess. That's how i see it anyways. I'm not sure how i could change the flamingo to 'match' better as you suggest
.
Although it would certainly be amusing to see a flamingo holding a knife by it's foot, i dont think it would be practical for game play..how would he attack+move at the same time? XD Poor Larry would be making himself a gimp! haha
anyways here's an update
I don't really like the character stats but i can't think of anything else -_-;
