I haven't been active in the fan-comics community for a few years now. In terms of quality, you need to put more effort. When you resize sprites in paint, they look really pixel like. I think there's a way to resize them without doing it by the rectangular selection tool, but I don't remember how.
Your storyline is also too fast paced. I can hardly follow what's going on. It is also kind of cheesy to constantly put, "Will such and such to this? Find out next time on ________".
Lastly, your spelling and grammar do need work. I recommend typing the script up in a program with Spell Checker (such as Microsoft Word). You can see your errors that way.
I hope I wasn't harsh.
