Well, because i like to do this scan a long time ago ( click here)... between other projects that i like to accomplished...
This maybe if you can see it's a little simple in background, but a lot of work doing the vector... (maybe *and most probably* you didn't like to know about the process...).
Well, this wall is made actually using more illustrator than photoshop, that's why i can modify anything when i like to do that... :D and the only thing that i do in photoshop is the blending modes and the blurring...

and why I'm motivated in doing this type of wall's?
because i didn't feel to do a common wall of the common scans of the common series that everybody loves... i try to do unknown characters or characters that are in manga or games that are not yet in anime... like the my following one: One Shoot Shoujo Manga Lineart
