you asked for criticism and I'll then give you!
please don't be offended! also I'm not an expert, neither good on this kind of pictures.. i've also tried some attempts and they were also bad!
so i'll give you my advice
these pictures are not that good, and I'm sure you can do better with your camera.
I had the liberty to go check what your camera is capable of doing.
it says your lens can reach a zoom 12X (36–432 mm)... so my advices are:
try to go as close as you can with your camera (i mean the zoom), to the moon.
use the manual mode if you've, if not, try some modes that your camera provides and try some and see the best you can work with
set your iso low... I tried high and it got shitty results.. as you can see in my 2 attempts : 1# 2#
i used some different ISOs, so try some and see the one you get connected with.
i'll also advice a tripod for night shots :)
i've not used a tripod, but for sure it can be helpful :)
