Made a lot of changes to the armor and weapons. Kept some of the overall style intact. Added a background and color. This scene is meant to communicate a desert deployment.
The background was a photo I got from google images then painted over. In the original photo the ground had snow and there were cars, so it's heavily modified at this point.
Yeah, the heavy armor is more of a Mech suit than body armor, kinda like the Iron Man Hulk Buster armor. I really need to revisit that concept. I think that's what I'll do tonight! Yeah buddy!
I imagine they don't fire on the fly. They would only really make practical sense if the suit had a special firing mode that makes use of an anchor support. Something like what mobile crane's and drilling machines have.
