This piece to me is amazing. I find myself completely enraptured by the whole swirling motion of the stars overhead. The barn is a nice contrast to the brightness overhead.
Composition wise it's well done, the eye roams happily over the entire piece at a comfortable pace and I don't feel like I'm stuck looking at one thing for too long. The brightness of the sky in contrast with the darkness of the ground gives it an even and balanced feel to it.
Overall this is certainly something I could see as a large hanging piece on a wall or in an office somewhere. Very well done.
