Deadline: End of march (But hopefully sooner!)
Minimum images: 6 Characters (If you want to draw a few CG images I won't complain... But that, of course, depends on the time and the disposition of the artist.)
Main theme: All characters need to seem fairly adult. Shiny-eyed SD would feel a bit out of place. The next spoiler should really be read only by any aspiring game artist:
The whole game passes in the afternoon, when the sun is setting, so coloring the characters accordingly would be extremely welcome, although it's not strictly nescessary.
Intrested artists can contact me if they wish to know more about the story.
