Art Sketches 1

Hello, I'm Lilyflowerstar.
I'm planning to become a manga and anime Artist one day. I want everyone's suggestion about my art. I don't care about bad languages of a thing about my drawings, I just want to know what I need to improve on. Since I've ran out of ideas of drawing stuff, please type out your suggestions on what I should draw. I can draw almost anything, but if you need it detailed, I'll need some time on it...
I just started working on creating covers, if you want me to make one for you, I'd be more than happy to.
No copying my drawings without me saying so.
Thanks! XD
