I'm sorry, but lame ripoffs aside, this thing still stinks. Too many different typefaces for no reason, white type on white b/g for no reason, type running over the central image for no reason, lazy lame cropping for no reason... c'mon!
The point is- just be cool & alter it SOMEHOW. You won't get any respect from your peers using Superman straight up. An even bigger issue is that DC will come after you with a 200lb hammer. Once they become aware this is out there, they'll start looking at the rest of the site trying to find shit, and then away we go.
If I had done this, I would be way too worried to post it on the web. I would recommend removing it for your sake as well as mine.
This is the kind of shit you can EXPECT a cease & desist letter for. Eventually, our whole little nest may fall to litigious action propegated by "artists" who are too lazy or uncreative to at least change SOMETHING. For shame.
