Rejected Batman logo sketch in marker for DC’s licensing department, from the early 1990s. I think this would make a pretty good cover logo, the one change I’d make now is to shorten the center point on the M, as it fights the point on the bat symbol.
Nice design. I like the way you incorporated the eyes into the logo. The only thing I am not too happy with is the outline. Overall, I like it.
