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.
I notice that some of your bw art is pure pencil (with some black inks) and some has grays in waterecolor...just curious why some get the additional step of washes. Don't get me wrong, I love the watercolors, just wondering why you only use it sometimes.
