Celts n cowboys?
This sounds very professionally made. Really reminds me of a piece my dad played back when he was in a brass band, called Cry of the Celts. At least the intro.
I like what you're trying to go for here, a hybrid between two cultures and historical eras. It's certainly interesting, and you do a lot of stuff right here.
The instruments sound crisp, very good sounds. Composition is also very good, transitions, harmonies, everything seems to fit.
Only thing I can complain about is the fact that the Cowboy part didn't shine through as much. That is, unless Medieval + Cowboy = Celt. The rhythm of the tunes are very reminiscent of celtic music, at least.
