Although this fits the theme, this photo isn't interesting enough I think, just the whole blackness and the moon small like that. Maybe you were caught up in just fitting the theme here more than making an interesting and good photo. It's good that you got details in it though.
The pure black background is dull. Having at least a slight hint of cloud light or some dim stars would have helped break it up without being too distracting. On the other hand, that's a really nice shot of the moon.
