Okay.
1) I love your scan. It's flawless, and it has robin in a pose I've never seen before.
2) I love the font you used for the title of the wallpaper.
3) I love the background and the slightly gothic feel to go along with Witch HUnter Robin.
This is my first fav. I am a big fan of WHR, and I am usually appalled at how Robin is treated. You have worked wonders, my friend.
