Pretty well done. Remembers a little bit of passages from Pirates of the carribean - especially the spiccato strings. The only thing which could be improved in my opinion is to bring in a more recognizable main theme. Its hard to follow a theme here - even it sounds very well :)
Your instrument Question:
* I have heared that "ERA Medieval Legends" is saied to be good, but i havent tested it myself. Maybe it is interesting for you.
* Other old instruments are included in EWQL Ra (Bagpipes, Hurdy Gurdy, Bass Recorder, Gadulka, Frame Drums, Fiddles, and lots of other instruments)
* I have seen a Dulcimer in EWQL Gypsy - its called Cimbalom (Eastern European hammered Dulcimer).
* The harpsichord i use is from EWQL Symphonic orchestra. Its ok - maybe there are better instruments out there.
* If you are looking for excelent church pipe organs check out the Hauptwerk Virtual Pipeorgans"
* A friend of mine loves the instruments from Spitfire (i think its a british company which also created albion). Maybe you could find something interesting there.
Hope this helped a little bit :D
