C: i like it! its a very very good drawing for your first and i love how you spent a while on it and didnt rush it! most people rush their first.. like i did XP
you may want to work on your anatomy a little bit though.. other than that its great!
another way to help you with the anatomy is to make a sketch of it first, then add another layer and do another sketch to make it look better. then you can start on the realisticness on another layer... (lol i confused myself >.<)
