This is nicely done (as all of your instrumentals are). Excellent mix.

As far as the ending... I like an occasional fade ending. And Andy's mandolin solo tracks always make good fade endings - the mandolin has a way of "cutting through to the top" of the mix in a fade - which makes the fade seem a fairly natural way of ending (or, rather, not ending...) leaving the ear "happy". I would think it would work for any submission type track, too...

Best to Di.
