Originally I wanted to set short haired Sanae as a theme but then it felt a little limited... Anyhow here's my take on the theme, enjoy! Since I was the one who set the theme, consider it not qualified for voting :V

If Pasu wins again, second-place gets the prize is all.
Also, I'm sure that if you just asked for "short-haired Touhou" you'd probably get a Sanae in there or somewhere.
The funny thing is that "Guilty Alice" itself wouldn't work very well as a theme either, which I think is kind of silly and sad. Something like "short-haired Sanae" would actually be quite fun to draw too, even though it's really specific.
We could loosen the guidelines to allow more specific themes, but I'm not too sure myself about this.
