Ok, the comic has a couple of key mistakes you shoudl edit.
First off, the text seems to big for the comic panels to handle. Try unsing the text "Smallfonts" size 7. It will make a lot of room in the comic and give you more room for the characters to move and for the viewers to see. Also, make the textboxes only big enough to give the text breathing room. Your current text boxes are too big and take up space they don't need to use. Also, try making the text boxes more of an rectangle with circular edges. I'm not sure if you use paint or painshop or what, but if you use paint, this should be pretty easy to find. Also, you need to add mroe punctuation/capitilazation in your comics. I've counted a lot of times where you didn't capitilize soemthign or didn't add a period at the end of your sentences. Work on that.
In comic 13#, you mispelled Hyper and put Hipper.
In comic 12#, you mispelled gonna and put gona.
Also, you seem to change up your comic style with the text and other things as the comics progress. I'd suggest finding on ecomic text style and stick wiht it through. One thing you could do is color the text boxes a certain way corresponding to the character, like what he is wearing. Also, the comic jsut doesn't seem very realistic. Not with pokemon, but I mean like how The character ran from the grunts, but the grunts beat them into the city, or atleast got farther than them in. Also, aren't Team Magma, Aqua, and Rockett all distinct rivals? I really don't know why they would work together...
And, WHAT IS THE PLOT? I don't have a clue what the plot is. You're going to random places for no atiquitly explored reason. Why go to Goldenrod? Going thee because the character wanted to shows me that you are running out of ideas and you are rushing the comic. Why did Jackson need a starter? He isn't going off to any gyms or contests, because you haven't showed us that he is. So he got his starter for no reason?
All in all, the comic needs some work.
