There's a big empty patch on the top of the subject that does not really work for the composition. I think you should have had your model turn the other way, so the craters were facing the camera. Yep,... that's what you should have done.
not obviously HDR (and yep I know it is) I hope those folks who have no idea how hard it is to take a photo of the moon without HDRing it don't mark you down. This is stunning.
Fairly regular telescope shot of the moon but I am struggling to see any HDR here.
Perhaps if you have a tracking device you could have taken a long time exposure shot to pick up some stars
