I liked the very finely textured pattern. most of the shadows till now have been large, we can do some detail work too. Google Image Result for http://designyoutrust.com/wp-content/uploads/2012/08/i1a29.jpg
Shape: The clever perspective of this photo brought these two spiral staircases together to create a double helix. It's an organic shape that wouldn't have been created if view from any other angle, so I think this is a really cool photo.
