You say you don't have a website yet: if you get one soon, go for something like DrunkDuck or Keenspace. Just a tip - they're designed to host online comics for free.
Your comic needs a lot of work, but, like Traitorfish said, there's potential, and if you're serious about it, sure, you'll improve over time. A few things you can fix up right off the cuff - DON'T draw on lined paper. It's a big no-no, in fact practically every parody of a bad webcomic I've seen devotes at least a little time to laughing at people who do exactly this. Get yourself a plain sketch pad.
Secondly, use speech bubbles rather than just typing words over your pictures - I expect, too, that this will be even more important once you start using colours - it may be possible to be experimental in this regard, but at beginner level, yah...speech bubbles. ^_______^ Also you seem to alternate between typing and handwriting your lettering - go for one or the other, it looks less clumsy and more polished. If you wanna stick with a type face, perhaps go for something more comical...there's a good list here: www.blambot.com
Once that's sorted you've got your basics down. With regard to improving you art, life drawing never does any harm in learning to convey accurate anatomy, reading a diversity of other works, comics on the web and in print will also help, and assist you in deciding on a definite style. For the writing, I spotted the odd spelling mistake and grammatical error. To avoid such things in my comics, I usually script and spell check them in MS word, proofread them there, then proof read them again once they're on the page. Might be worth a try.
Otherwise, yah, it's that whole 'practice makes perfect' adage. Good luck.
