I must admit I'm not an avid comic book reader.
It seems a little odd that you want to create your own comic book if you have never been an avid reader of comic books yourself.
Sort of like wanting to become a chef when you have no great interest in eating or enjoying food.
I can tell you what I like in a cartoon strip, and why I'd continue reading it, but unless you've also had a similar first hand experience, I'm not sure you'd really understand it from a reader's perspective, and the same would be true of comic books. Graphics are only a part of it, and probably the smallest part. The storyline and the characters have to be consistently interesting if I'm going to keep reading, and look forward to reading more.The ones I enjoy the most are those that seem fresh, and keep surprising me, no matter how long I continue to follow them.
