Not bad
If you made them move their heads, bodies, or even their arms while they talked, I would have liked it a lot more. It was a little bland in the animation, but I still 5'd it for creativity.
-Sound quality - great
-Picture quality - pretty good; high-res
-Animation - only seen in Hulk/ Wolverine's mouths
-Plot and voice script - pretty good
If you have them move while they talk (assuming their arms aren't permanently attached and immovable), re-submit this and I think you'll get better ratings.
