Humm...
So, it looks like you are super influenced by the "Bleach" Manga. My suggestion is to use some Mannequins to help you with placement and proportions. Also I think you should concentrate on how you draw hairXD Even for manga it looks impossible for someone to have hair like that :/
Also you should branch of into your own style than try to imitate others XD" It's not a good thing in the long run XD"
It's a good start thou. Keep on going and you'll get better XD
