This is a spectacular piece! The wonderful shading, blending into the distance and motion blur really give this a perfect sense of action and realism. I especially like the use of blues in the foreground to give a nice 'edge' to enjoy.
I like this piece because typically astronauts are in a space-Iike setting, naturally. This wandering person seems completely out of the normal element and I think it's a fantastic idea. Makes one wonder why. Nice coloring as well
