I am so jealous! I wish I had your lens!! I am getting a camera like yours though! Anyway...enough about me and my envy.
The details are amazing and I like the tones too. Needs more negative space. The square crop doesn't help the image at all. The one major reason this picture did not get a high score from me was because it is a moon. I love the title, very cute and funny. I bet you have a great sense of humor. But, I just don't think that I would purchase a card for a couple with a moon on it unless they were scientist or something to that nature.
