New to SAI

So everyone has it. I have been using Macromedia FX 8 and it's been alright for me, But it doesn't have everything I need. or what would help me improve my art ya know. So I got SAI and I've just been playing around with it so I know what each brush does. But I think I'd like some help from some people because I'm completely clueless. as you can tell idk you don't have to.
