You're a good writer, believe me, you are. You have a good base and good ideas, you're creative. You sound great.
But...part of that is looking good too. What I mean is grammar and punctuation. The chatspeak doesn't make you look any better("u" and "ur").
I used to write on a site for constructive criticism. One of the things people used to do to help each other was have something called a reg. I still don't quite know what it stood for, but basically it was one of the author's regular readers who volunteered. the author would send them the writing via email before posting it, make corrections(usually in a different color), and send it back.
It's just an idea and again, I'm not trying to be mean.
