24 hours of Flickr

To my four readers (Catón dixit).

Can you please help me select the best picture in this set?

24 hours of Flickr was an event in which Flickrites from all over the world documented their day in pictures. The best picture from that day is to be added to a pool, whose pictures will be printed in a book.

Given that my day was mostly spent indoors, and frankly I'm not that great as a photographer, I'm not sure which one is really the best.  Can you, dear reader, give me a hand?
