I think that's because it essentially will be a combination of a fic and character generator. :)

I can't really come up with any ideas to help you though. When I try and describe pictures I like I get sentences that sound like I've been reading "Pretentious art critics for Dummies". For example:

Modern media used to evoke a traditional and strangely otherworldy feel.

The focus is on a gritty and dynamic character with a strong sense of purpose.

Vibrant colours are used to create a sense of passion and urgency.

I could keep going, but I think I'd only embarrass myself and possibly make people wonder what the hell I've been looking at :D
