Actually saw this drawing a week or two back, meant to comment. It's really a wonderful graphic piece that makes good use of cross-hatching juxtaposed with bold outlines. Also love the mirroring of the tree branches with the rocket's roots. Great concept. I do wish it were a little bigger, so the detail popped more, and I'm wondering if you could have dodged out some of the paper tone. Even so, I can tell it's a nice piece.
