Head and chest needs to be more serious and less colorful. The rest is good.
also what does the back look like?
I'm not the modeller, just the concept artist. I was suggesting additions to the model while filipe1020 was modelling it.
But yes, I did think it was a little too colorful. We'll tone down the colors.
Speaking of colors, the model will be rigged so it changes color depending on what the color of your torso is.
Here's the back. Jet shoes, booster on the back and two fins.
