Dammit
You're not giving yourself enough time to do this steven, what you're dong wrong is you are not focussing enough on the drawings, every now and then it starts to look worse than something that I could do, and this is something that you should look out for, cause otherwise your series may turn out to be one of those duds that stop after it becomes popular.
Steven, if you can, try to get a Graphics tablet, (one of those pens that are used as a mouse as well), they can help a lot with your art, oh and like that other guy said, ease up on the light that comes off the characters face
