That's a pretty cool view there. Overall it's nice looking, I would suggest darkening the background sky some more. For the Milky Way and the stars to be as bright as they are it would be because the background is equally dark.
That is a very nice shot.
I think the sky is a bit bright, but it blends very well with the foreground.
The thought of stitching that many 15mm shots gives me a headache!
