Not to go completely off topic on your awesome drawing here, but thought out comments it just something I try to do on the reg on all sites if I can, now I can't say everyone or even some people will do the same, but when I see such a great piece I really like to go over it and savor all the details, and feedback to me is the most important aspect of art communities.

This is really amazing! The coloring and shading are outstanding. I love the effect of the sand and the golden hues. The brown line work is a very nice touch to this piece, and I really love the expression of motion in the clothing material. Also, the reflection in the goggle lens is ace and though slight, gives a lot to the atmosphere of the whole piece.
