Awesome cover! The "T" shaped composition with contrast between the angular letters and the curve forms of the figure really drive the upward punch motion. The word "She" is hard to read, but presumably only for those unfamiliar with the character.
The figure is, as always, outstandingly beautiful. You struck a gorgeous balance between lean muscle and vivacious curves. For example, the up thrusting biceps show solid definition but is supple enough to avoid being un-feminine. The legs are similarly shown in great she-hulk build.
The pose is apt, with a clean, clear silhouette that plays very well for her feminine features like waste, hips and buttocks, but especially the legs. Finally, the facial expression is very readable and compelling--it conveys believably the emotion of a person crushing through solid blocks.
Thanks for the info. I've experimented a bit trying to get rid of the grainy pencil look in photoshop myself and it's definitely tricky. Adi Granov has done some super smooth pencil work, but he uses watercolor as well I think.
