Hey!

I've long been a lurker here, and always wanted to make submissions, but lacked the technology/knowhow/internets to do so. Finally I've moved away for university and now have decent internet and a scanner so now I might give it a shot. Anyways, I'm not so hot on computer art so I'm wondering what is the bare minimum of computer editing I could do and still have a shot?

For example (this isn't a future sub, just the most recent thing I have) :


I know this is not ready to be submitted, but why? What should I do so this would have a shot? Go over the black lines on the computer? Re-color it completely on the computer? I dunno. Basically I’m just a poor nub looking for advice on how to make my stuff look nice. Any help is appreciated!
