Subject: Torn on this one. It is minimalist and well balanced due to crop, but seems less than interesting which detracts from the whole.
Concept: Good Idea, perhaps the division (space) between the two is what is causing me to not appreciate this image as I should.
Challenge: Bit too much detail in the top portion of the branch. Almost side-lit which does not lend well to the concept of a sil.
I like that you were able to capture the moon and generally a silhouette of the tree, but then there would be no moon if it was a truely backt lit. Other than that, I think it would be a really cool shot without quite so much space between the 2 objects. Perhaps a lower and closer point of view would have allowed this.
Two points: 1/ A better balance is needed. If the space from the bottom to the tip of the tree matched that of the top to the moon, the composition would have felt much more connected. 2/ I don't like the title. How about 'moon & branch'? 5
