there is zero shading in the pic and you went outside the lines in quite a few places which tells me you didnt put all that much effort in but if your just starting its to be expected
my adivcie:
- stay in the lines (this is a must if you want any kind of decent looking pic)
-start shading your pics ( its hard sometimes but the more you practice the easier it gets)
- take some tutorials ( there is some good one on deviantart)
