So here's how the mech turned out.
I named it the "Z-2 Hammer Head", here's the final rendering (I still may go back and throw on some rim lighting):
And some color variations. I kind of like the "multi" sponsored one more than the "coke" one -- it has more of a NASCAR feel...
I really like how a lot of this page came out, so hopefully some of it will make it into my portfolio:
I did some orthographics and more sketch pages as well, but those are not really worth showing.
Thanks for looking!
