This photo is absolutely breathtaking, making it very hard to critique!
CHALLENGE: For rhythm, this photo may be a bit busy. There are so many examples of rhythm here that you might want to focus on just one thing, like the pattern in that amazing ceiling.
TECHNICAL: I think your camera was set perfectly. There is a light at the bottom of the photo, and I can't decide if that's your flash reflection or someone elses? This is probably something you'll want to edit later.
POST CHALLENGE SUGGESTIONS: I would stongly considered cropping out the bottom of this piece. The eyes are automatically drawn to that amazing ceiling and everything else adds an element of clutter. Don't get me wrong, this is an absolutely GORGEOUS print that deserved a high score!
the bottom of this photo with the match sticks could have been eliminated by cropping to keep the viewers attention on the cieling.. nice exposure though.
