Messy style is awesome and in now days. WORK IT BABY WORK IT!
Humor aside, The cape/hood thing is great looking. I really don't know much about his personality personally, but from what I have gathered from various pictures, it fits him well. The strings added make him look like a puppet master of some sort, which in fights, we all know that's an awesome technique. I'm going to guess he's in virus uniform but one thing in the hood design makes me think. I see you were going to make the green/teal stand out, but the red on the inside just shakes the whole color scheme he has going on. Maybe you could try using the goldish color in his eye with a reddish tint? This is just personal opinion, but I think it would help his color scheme be a bit more held in together.
Art wise, your messy style is fine. the textures are good enough to be able to see where hair is hair and cloth is cloth. and your shading is awesome. It's well held together. I would like to see some more pictures in the future like this from you, they're awesome. C:
AGUTH, OH AGUTH. WHY HAVE I NOT COMMENTED ON THIS YET OH KURU OF GREATNESS.
Okay, now that I'm done with that 8D I personally think you got the messy style down well. It's all.. fluffy and pretty~ Ah, your hair.. well, not your hair, but.. xD Idk how you manage to make hair look that sexy.
AND like.. gahhhhhh his smile is incredibly melt-inducing. Yay, Yukito <3 I've always liked him.
