Hey Michael,
Fantastic looking clouds! Love those soft edges and you've sorted out the lighting pretty well!
I think it is a common 'mistake' to fill in every empty space of atmosphere with planets/moons/constellations.
It might look nice sometimes, but most of the times it makes the image 'too busy' and it destroys the composition or withdraws you from the area of interest which is in this case definitely the clouds themselves. I also doubt if you can see constellations with this type of bright daylighting, but that's just another thing.
