Kay. I'm done with this. I still have a lot of things to know. Like what each of the tools do. Like burn which I'm not so sure of. Please help. Thanks.

This is the very first time I've ever drawn on programs like this and I don't have a tablet either...so please don't freak out that its ugly or anything. :]
Oh, and btw, if you have any tips for me (like how to make it look like those elite bastards' paintings) please do share it, thanks.
