Looks like a stylized Piranha Plant from the Mario series to me. Those don't have eyes.
I'd suggest starting off by adding one more darker shade to the colours, and perhaps a dark gray that can be used universally to shade any colour. The mouth would also look more interesting if it was a little bigger and would show more depth.
