Sorry about the wait for your critique, this is coming out of the backlog!
Some great detail in this shot! The craters near the top, and the lines all over the moon. I've taken an astronomy class but have since forgotten the name of them.
Anyways, I'm going to have to agree with the other commenters on this shot, its great but that frame hurts it. It's just too big. I gave you a 5 but had it not been for that frame it would have been a 6.
