I'm a bit mixed on the art. It looks good but also a touch rough, like some excess line needed erasing out or something. It also looked like on Superman there were scars? (!) Maybe from the tests and they'll heal when he gets re-exposed to sunlight? In the preview it also interestingly suggests how strong Superman is if he can basically bench-press the weight of the entire planet over the course of five days and only just begin to break a sweat through a single bead of it. Tells you a lot about how much he has to holdback when fighting or doing anything, really.
