Backgrounds: 10/10
You used overall good background from a game, and each panels is in accord with the one before.
Characters: 8/10
Hm...you did their personalilty very well, but, there's something missing.. I can't quite put my finger on it...
Text: 5/10
Tsk. I don't like how you place thoses bubbles texts there... it makes it hard to read.
You would want to make your comic bigger to be able to fit them in, and make the bubble text WHITE.
Overrall: 7/10
The comic had a good, old-style feel about it, but it's not that refreshing. And...I find that you're off to a very good start for your first comic!
