I haven't watched D.Gray-man, so I have no idea who this Allen Walker kid is...but he's one awesome looking person, isn't he? =D
No brushes on this one--everything special was a Photoshop effect. The original render of Allen came from here and was done by starfox66, and the nifty blue coded background made by Dave Bennett came from here.
I dedicated this to Felcie for making such an awesome wallpaper for my contest <3 I hope you like it!
