Some advice on writing?

I really suck at proper grammar usage. I um... admit that spoken english is NOT my first language. However, I learned how to speak maybe when I was 5 or 7? But sign language was my first language and some of the sentences I write just don't really come out right... they come out all jumbled. xD Just a heads up on that one. But I always had very good reading comprension. I can understand new words and their meaning when its in a paragraph.

Anyway... I'm not sure how do you go about writing a fantasy story. Not like... LotR/Matrix crap... something like well... Advent Children almost. xD Nearly realistic in world views, but magical when it comes to some people. And the themes are usually sometime uplifting and depressing at times. I really have a lot of ideas for stories... but I'm not sure... how to go about it. Should I go all out and have someone throw me some crit or just do a short one to show an idea?

And finally, should I read books to improve my grammar usage? This is what I'm actually afraid of, I do not want books to give me an impression of a particular style that they use in writing. I'm pretty darn sure that nearly most writers have their own style in writing besides the story concept. I'm sure its important... is it?

Let me know and I appreciate any advice or crit.

Thank you guys, I'll look into it.

In high school, I took a creative writing class. I realized from Sol's post that my teacher royally blew. Yeah she pretty much suck at teaching that sort of thing. :\ I remember loving how to write with such freedom. I always have something to write about!

There's nowhere I can't reach.

Okies, thank you guys! Keep them coming!
