These are great sprites! Really digging the colours, movement, and expressions here.

for a comic book and pixel art fan this is mad good

They even look great individually!

oh boy do I love this. Looks amazing.

These are so fantastic

Much better!!! 

I always wanted to make X-men, though based on the Sega Genesis version. 

Avengers logo removed!

The sprite are great, the logo too, but not is pixel art!!. :/

Indeed, you have to remove the logo or the piece ain't gettin' accepted, yo!

Awesome sprites, BTW! How about you do Days of Future Past next? X-Men vs future Sentinels?

Because it's not pixel (and not your art too). Very nice sprites though.

Oh... Why so? Is there a rule against official logo? Or is it because it's not pixel?

The sprites are nice though i'm fairly sure you won't get accepted into the gallery unless you remove that downscaled Avengers logo.
