Great job with these avatars guys! Keep 'em coming! For some of you, I recommend also trying lighter and brighter palettes.
For example, if you want to do a dark shadow, rather than going for grey or black, try a soft blue instead. It creates the illusion of being darker, but just 'glows' a bit better than a purely dark color.
Also, sometimes using weird combination of colours can have a fun effect - like pink + turquoise + black or something. There's a site here where you can play around with some colour palettes for fun: Kuler
Here's some more from me :) Monkey + Sinjid.
