Drew this guy up a while back, but just recently touched the image up in photoshop. Enjoy:
if my skills were better, the geometry would not look like I was working with '90's polygon levels I plan on redoing the legs and the arms at some point, so they're less bland, but I think it looks OK for what it is at the moment.
well, i decided to make my version much less stooped/squat than the original art. i also think the towering, lanky silhouette makes the mech look more menacing.
