Panel 2: Revolvers are, I find, notably more difficult to draw than semiautomatic pistols—but harder still is correctly drawing the hand gripping a wheelgun, as the positioning is a fair bit different than the easier-to-visualize image of a hand gripping a semiauto. So, yeahp, kinda screwed up Emp’s hand holding the revolver, here, though the panel’s cropped off in such a way that the flaw is tough to spot.
And yeahp, in case you’d forgotten, this is the same high-caliber revolver that Thugboy used to (futilely) shoot a frozen Willy Pete in the face back in Empowered vol. 3. In fact, I’m pretty sure this panel’s gun is photoreferenced from the same source used in panel 2 of that earlier flashback scene.
