Infantry Mech, Finished

So here is the finished Type 21 infantry mech drawing.  I've got more of an idea what I want for this mech now, and the characters associated with it (pragmatic, blunt, mercenary, survivalist, suspicious).  It's not the final design, but a step in that direction.

I started it with a ballpoint sketch, and colored it with Prismacolor colored pencils.  The lightest tones, from the primary light, feet, and reflected light were Cream, Beige, and Cloud Blue.  The midtones were mostly in Warm Grey 30% and Cool Grey 50%, with Cool Grey 70% helping out in the areas to be shadowed.  The dirt splotches and dusty tone around the legs was with Light and Dark Umber.  The secondary light was done with Blue Slate.  For the darkest parts, I used additional Cool Grey 70% and Black, and used Ultramarine to hint at the secondary light on the dark parts.
