Good start! You might want to adjust his proportions a little in order to balance the upper body better in relation to his lower body. Here's a pic of the original boxart so you can maybe add some extra detail in certain areas. The face/head feels solid! Try and add some bevelling to the edges of your objects to remove the "boxed" look of him. btw. I have a set of 3d hands lying around if you're interested in taking a look at how I made them? Just let me know, keep up the great work... C.
I'd love to look at a set of 3D hands...so far I've been making them how a set of robotic hands would look like in real life (attempting to anyways, because we know metal can't bend like skin can.
