Well, the kind of 3d look of the background kind of clash with the 2d look of the character, but all in all it´s not too bad.
And a guy with his scooter is never wrong either. The character looks sharp, nice and clean.
The grass in the background with the trees and vegitation, with the text is a nice addition that adds detail.
Detail that do not take over the character, which sometimes can be the case. And it´s hard to balance detail and keep the integrity of what the wallpaper is really about.
The rainbow is a nice effect as well.
But what i think is the best part of this wallpaper is the straws of grass around the characters feet, very detailed and very well done.
But when it comes to the text in the grass, it do not exactly look like it fits.

Wow a HxH walll :p there are too few !
And pretty good work, I think you should leave the blank part at the left, a too loaded wall is not so good...

Very pretty wallpaper! I think it's well-done overall, not to mention it involves Killua. :3 I only have a few suggestions. The extraction is rough in a few places. I would be more comfortable if the outlines were smoother. The grass should blend in better with the ground around Killua and the scooter. One last thing: I agree that the text in the grass isn't necessary. The cute little Hunter x Hunter logo in the corner is enough. ^^ Good job! I love this wall!

It's really fasinating...
But the name isn't there.

Awww i like the rainbow in the back

Not bad though except for the background and the character image doent suits well

Killua, my brother, I'm your techer to be a assassin (what!) Nice, but the background looks strange with him, I think. that's ok

Great rainbow effect!! 0.0 how did you make it??...however its a good job in genneral...I love KILLUA!!!!
