The roughs look almost exactly like the final except that he was a girl in the roughs, and a fun detail is that his helmet and boots are the same as the shotguner, implying that he picked them off of a dead soldier.
With the ideas, with the looks, the style, the details, the tridimensionality of your drawings... everything.
