It's your song man, do what comes natural. The biggest issue with asking for people's input is you will hear THEIR ideas for where to go, which is only what we hear. The best strategy for coming up with a song that you will like(not the general population) is to compose the song instinctively, and not strategically. If that makes no sense... I will make it very blunt for you... don't THINK, just DO.

Listen to the song straight through(with the looping on whatever it is you use to listen to it with turned off) and the thing you hear FIRST after it's stopped, is what you need to try and put in the song. If you draw a huge empty hall of silence in your mind, then take on suggestions, but try to do it your own way first. :p
Also, a Clavinet and a Dulcimer? Weird combo but you definitely made it work.

You would've been great for the contests I threw back in the day. I THINK I have a good dulcimer, and the pan flute I have a good one for that too. Actually have this set called "World Combo.SF2"(this is assuming you are using soundfonts?) I can upload for you if you don't already have it. Has a pretty good collection of foreign instruments. Bass samples... I might have one but not sure what the SF2 one I have sounds like. :p
