i think your doing great. i read through a bunch today. it's a good story and the artwork is cute. i can see improvement since the start in both the art and the lettering and that's always a good sign.
nice that there are a few solid comics out there that are not only kid safe in content, but that kids can actually relate too. (school spirit and cottonfluff hollow come to mind). i think cooties is a nice addition and wish you luck.
