No problem!
You should get your hands on a scanner if you're drawing your work by hand. Even for print comics it's going to go into the computer at some point. It's good that you can recognize your art is still rough - I would work on making it more polished first, there are lots of tutorials online about how to do that, here on DA, on YouTube, all over really, just do a search. "Comic book artwork tutorial" "Comic art inking" etc. Practice, practice, practice, get your work as best as you can, as good as the comics currently being published or better - THEN worry about publishing. In the meantime while you're getting to that level, post as much to the web as possible - get feedback, make connections, make friends, support each other. Always be nice, but always be honest too. And don't worry about people stealing your ideas from posting on the web - just make sure you indicate that you're the creator when you post your artwork and you should be fine. DA does this automatically with everything you post, so it's pretty safe here. People borrow and adapt other people's ideas all the time, it comes with the territory, but if it's outright plagiarism you can always point to your original work if/when you see someone ripping you off. I have been in this very situation myself - and it always worked out in my favor, the web is very democratic that way.
Good luck!
