My first vector

Ok here is my first ever vector done in Illustrator. I know its ****ty, and i have no skills yet, thats why im putting it here to see what u guys think and give me some suggestions on how to retouch it. So please as much of HONEST critique as you can possibly give me. I want to learn how to make nice lookin vectors.
