Hmm... decided to give yourself a try in sketching I see. Very nice.
Anyway, how can I put it? It's kind of normal to don't expect much when you don't have experience. But it's a matter of studying "things" (anatomy, perspective and stuffs), practice and how to use tools (such as color pencils, white pencils and even eraser).
Aaaaaaand...
No, I've meant "Is my picture worth uploading on imgur? It's bad anyway." 
I think that doesn't matter. How can I say it? Art is all about... missing. You miss, miss, miss until getting it right. Yeah, I know. Complex. :p
Buuuut... a nice try. o/
