It's a frog, Matrix. A frog! DX Or rather it was. I like the grasshopper better than the frog, though they are a lot alike...so 6/10 I changed mine because I saw a bunch of other people using it.
That one doesn't really appeal to me the hair isn't really well drawn and the glowing aura around her sort of puts me off it, 4/10. .. Calvin's armatar just changed?
That is epic and the different shades of green are rather nice, the crocodile looks like it's happy as well, and smiling gets you a better rating! 8/10!
That monkey looks rather psychotic, almost like he was about to kill someone, so I guess it represents your personality for that reason, 8/10. It's not something I would use, but it does look pretty decent.
