Pretty cool! I like the design. I made a color edit, as right now the colors seem a bit dull. I like having the main character really pop. As for the shape, I think the right (our right) arm is too short and it looks like the metal band encases his elbow preventing it from bending. His feet are also really tiny. Keep up the good work.

Ah, thank you very much for the review, i really appreciate that. But, honestly, the color you using is too much luminosity isn't ?, which is burn my eyes.
