It has been my inspiration for a while now so I thought I would compare my skills. I spent 5 hours on the polly modeling in Maya and soon to put it through MudBOX.
Just want to make it clear that I did not come up with the concept for this marine but used it as a little practice for myself as I thought it was quite epic. Vitally Bulgarov based his design on the StarCraft 2 Marine.
