Oh. My. Dear. God.
First of all, get a real background, not just some random lines.
Second, don't resize images, leave them how they are or go to image-stretch/skew, and stretch it by 200 on both sides.
Third, get waaay better graphics, some badly drawn paint default colored bubbles don't cut it, go to the spriters-resource.com and get some graphics there. Also, the battle screen, there are some stuff there for that too, make sure you replace it.
Fourth, always make sure your using SPRITES, for your battle setup the poke'balls on the side of the badly drawn screen are sugimori style. At least I think it's sugimori style, well, whatever it is, it's not a sprite.
Fifth, Don't use cliche plots and overused jokes, the 'ole, 'I'm going to kill the author,' not only breaks the fourth wall, but it is extremely overused. And the idea of getting a first poke'mon and battling is cliche to the extreme.
Also, work on your speech bubbles. You should use the rounded rectangle thingy, whatever they call it nowadays, instead of the line tool.
Good. That's it for now.
(If you didn't understand any of that, I'll make it simple:
Read a tutorial, work on your comics, and don't pay attention to the horrible critisizer that will say you suck. Just work on it.)
