I wouldn't call the image "poor taste" or kitschy... but, in my opinion, if it wasn't so processed (for lack of a better term), it would look better.
I'm no expert in taking pictures, but even I can quickly see that there is no way that the image is just one shot. The moon would blow out the stars.
I think the backstory on the webpage takes away from the image. It leads to questions. Just give it a title and a price.
One thing is for sure, he is getting lots of free publicity here
