This is a very funny manga I found a scanlation of some time ago. It's about a girl who gets projectile nosebleeds whenever she sees the guy she's in luv with (or even a picture of him). The wall's pretty basic. I just took some panels from the story, and selectively colorized them for heightened effect. The red spots in the background are supposed to be bloody drips. I'm not sure how well that worked out, but at least it gave it some texture. Have fun!
