Its nice - I like it for the detail that you don't normally get with a full moon - and I especially like the mountains seen in relief on the left edge.
However, in bringing out the detail, there are some features that have been left with a white 'rind' around them - like the small craters near the centre and the whole right edge of the disc.
If you can keep the detail, but tone down the 'rind' a little - it will be a cracker
