Hmmm... I can tell that the camera is looking up in this shot... The subject matter of the photo is not screaming at me to continue evaluating the shot.
I know you're probably getting a WHOLE LOT of comments about this tongue-in-cheek picture not filling the requirements of the current challenge. Whatever. Personally, I gave this photo a lower score because it was hard for me to determine what the photo was trying to present. Is it the Earth From Above book? There's some nice color in this picture, but no real strong focal point or texture to the picture. To be honest, I'm not sure what I would have done with this photo to try and improve it. It's a very challenging picture that you've taken, and that's admirable.
I'm sorry but, couldn't this be considered copyright infringement since the book is primarily the subject? I mean, yes, it is an original idea but, that's what it states in the rules. Unless perhaps you had the written permission of the author of the book to use his/her image for this pic.
