Sweet, I really like the design of it. I also love the colors you used! The only crit I have right now is that the shiny plate on the shell doesn't really go well with the others. Maybe just making it not shiny will help, but I'm not sure... Also, the blue "pipes" on the side of the shell make it look awkward, because I'm assuming the blue is the skin, but the skin doesn't come out the sides of the shell like that.
