Its a pretty lovely wallpaper, Yeah I hate Mitsuki..... I'm still so mad at her.. I couldn't care less if she had a car accident and went comatose... I only care for Haruka... she's so innocent and sweet. Anyways back to your wallpaper, its pretty good but I think you could blend the scans a bit more. Maybe make a gradient of light blue and darkish blue and set it to overlay.
Anyway's still going to fav =)
Good job and keep it up,
