I don't really like the sig that much, for me it's too sharp, mainly the text and the effects on the cut, but the fact that it takes up so much of the sig is why I don't like it much. The background is alright with the 'SAVIOLA's in the background and it's a good colour.
The hair on the cut is pretty bad but it's always hard to get right. And IMO you need to take more time cutting because bits around his neck, hands and shoulder are really sharp when they turn, it needs to be more smooth.
