Excellent shot of the moon. Sharp, sharp, sharp. However, it doesn't say zen to me.

Wonderfully done! The moon could be a little sharper, but that's just nitpicking.

This has the simplicity that I consider consistent with the idea of "zen". I like your composition, with the large amount of negative space. I rated down on image quality due to the readily visible blue channel noise throughout the sky areas.

i feel it would have been perfect if the sky was dark for the zen theme.

Fantastic. I really love pictures of the moon and you've done this one very well. High from me since it gives me a lot of peace to look at it.

i think you got it here; it is what it is (zen)

I like this a lot!
Reminds me of the Apollo days too.
