WOLF12, i'm no expert at all myself but here are a few tips:
~ don't make spelling/grammar errors! They make your writing look unprofessional and in my opinion, quite hard to read.
~ use good, complex words and sentences but don't go on and on and on...
~ describe your characters' feelings, emotions, and so on very deeply, but don't make it too long and boring.
~ don't jump into a book thinking that it's all going to just come. Make a plan (doesn't need to be on paper, just in your mind) that doesn't even need to be that complex. Just think of an idea, the orientation, the problem, how your character hopefully solves the problem without being killed and the resolution. Doesn't even need to be overthought, just make sure you've got a clear idea and write!
Hope this helps,
