Shadling Shades Well.
Really, the shading is one of the best parts in this drawing, and when I say that it includes the lights reflecting off the metal and goggles. The red outline gives it a feeling of..how do I say it, a feeling of dark and powerful, and the color pallete is small but very well used. I don't really know how to say this properly, but this is perhaps perfect. I can find no flaws.
