Actually, I'm learning 3D right now, part of the reason I've been slow on many projects and I'm hoping to make this guy, with some enhancements, my first full-fledged model. By 3D I mean Zbrush 3D sculpture, not low-poly game models which I already make.
The armor is a bit weird to be honest. I think the shoulder plates and the boot is fine, but the rest seem a bit out of place. The ab-plates make the char's pecs look a bit weird.
