So I've been working on this almost constantly since the last WIP post but I suck at keeping it updated properly.
I've toyed with the idea mounting the machine guns off of the backpack for a gun cannon type look, but I tossed that idea It just didn't feel like a good fit. Anyway, from there I've tried to re-sculpt a few things like bulking up the lower legs and I've added a panel line to the thigh to disguise the seam line there. I'd like to think that I've made a few tweaks to the head sculpt to give it a more aggressive look.
On a side note, I'm pretty pleased with how well it can stand up on its own.
