My only complaint is with the lettering. A better comic book style font would be a massive improvement. This font doesn't appear to distinguish between capital and lowercase letters, while traditional comics lettering actually does so distinguish.
For an example, look at this panel
in which Luke Cage confronts Doctor Doom. At a first glance it appears to simply be all caps, but look more carefully at Doctor Doom's dialog. "I knew it had to be you!" "I" the personal pronoun has crossbars, while the "i" in "it" does not. That is because the personal pronoun is capitalized but the word "it" is not.
