As much as I want a square-themed comic to succeed, you really ought to make an effort to put all of the characters in the same style. Since most of your sprites are from FF6 in this comic, I would suggest whipping up a FF6-style Cloud.
Also, something that has become my rule #1 for sprite comics: Resize your sprites to be at least twice as large as they currently are.
Thanks for the advice, but I prefer the sprites to remain in their original size. As for Cloud not having FF6 style sprites, there's a reason for that...you'll just have to wait until the comics explaining that show up.
