Hi everybody!
First I know this pic is in such a poor picture quality it's hard to critique, but I wonder if you could give me some overall tips how to improve...

Iv'e drawn for about 8 years, less and more seriously, but I've always lacked in fundamentals and I understand now I will never get to the next level if I don't get this right.

So I'm gonna start drawing simple objects as still lifes.

ANY help/advice is appreciated.
