Very nice, I like the simple design. The shapes and colours make the wall, but some of the lines are a little jagged. It's hard to avoid jagged lines like these though especially in situations like white on black when it makes them really noticeable.
I think the only think that would make this better would be one more colour in the hair, other than that I think this is very nice. Good job!

That's a really different perspective wallpaper compare to other from your work =3
I like this one tho hehe ~ It's simple, yet give us a mysterious expression ^^

very mysterious wall
who is this guy hiding in the dark its Allen
I love this guy
its a nice wall Arya-chan

i like the interesting perspective and the way the background contrasts with your vector the vector is done nicely although the lines are a bit jagged [hope i didnt offend you ] i like the simplicity of the background and the limited amount of colour gives it an interesting touch nice wall ^^

very cool, i like the contrast and the darkness

I like it when Allen looks evil and mysterious. The contrast between the black background and Allen's white hair really stood out to me. Like booniechick said, the lines are kind of jagged, but I still compliment you for making this wallpaper! Keep up the good work! =D

I like it. the simplicity of this one is very mysterious. Especially that little smile on the corner of his lips. very cool vector!

Very mysterious...I like it.

Very simple, but it's looks so cool.

Nicely done, i like it.
