The "e" seems a bit forced, maybe put Wolverine's claw sideways and make the "x" from Professor X's wheelchair.

Id buy this the second it comes out. Any chance a shirt will get made soon?

Wolvie's arms need work. Otherwise quite good.

I would like it if it had Cyclops somewhere. Maybe for the I. An optic blast.

@Hisc it spells -COEXIST-

I think it is awesome. I got it as soon as I saw it. I'd love to have this as a bumper sticker.

The idea is good, but I'd take forever before I could imagine the meaning. The X is obvious, the E is obvious, the S of superman is obvious. But B for batman, C or A for captain america, S for Spider-man and M or T for mjolnir or Thor are pretty obvious too. Why not the letters being of the heroes name? Captain America, Omega, Electra, Xavier (professor), Iron Man, Superman and Thor?

I think it would be great to see it in a minimalistic way. Like the shield, for Captain; the greek letter; the "fork"; the chair; the arc reactor with part chest armor; the S; and, then, the Mjolnir.

01:05:00 or 18:54:00 are the ones I like best. :D

I would just use the superman "S" not his full body.

If you just make the "Superman S" just the "S", I think you've nailed it.

I never saw the other versions, but I like this one. Even viewing the thumbnail in the email I received, I was like "Oooo, nice"

Actually, now that I think about it, forget the motion blur of the batarang, I think simply going with only the batarang for the C would be best. If you do an image search for batarangs (I used Bing) you can see lots of samples to go by. I think that will be much more effective. Good luck with your design!

That can be one option, where the motion of the batarang curves to make a C shape, or you can design it where the batarang itself forms the C, though that could be a little tricky to pull off. Great idea though, yaaay comics!

Great idea, but yes please work out the details like others have mentioned. Also, I don't think the bat tracks really work either, they're too overwhelming. Why not try using a batarang or something to make a C shape instead.

I'm wholly behind the idea of re-doing this, particularly with things like the Wolverine claws being swapped out for notably higher quality (preferably wearing costume).

Terrific idea, but the individual images need to be more consistent with one another (note the detail on Spiderman & Superman in comparison to Wolverine).
I personally think a much more minimalist re-vector of what you have here would improve the design overall.
