Beautiful tune, Gary. I love that genre' (Celtic?) with it's moody minor-key melodies and chord changes. If I had one criticism, it would be (and this is just me) to not do that little double-blip thingy at the beginning of most passages; or at least, use it more sparingly.
I don't do this type of tune because they are so pretty in their own right that any attempt at improvisation would ruin them. Okay, cliche coming: Nice job.
