Making the OSR games you really want.
It's a great cover design, however you decide to use it. Although part of me thinks you should rip-off a bunch of Marvel art in order to be true to the OD&D aesthetic!My favourite is the last one, with the toning.
haha! I could just put the Avengers on the cover to really sell a bunch.
I like all of them, but I'm more partial to the last.
Another vote for the halftone, looks great.
