I did take a long time to work with that first theme, sitting at the piano in great doubt :) - it all grew from that. It is in 11/4 time signature and with a lot of sus chords which I love. I am very happy that you hear the it as playful - that was my intention and important for the images that will accompany it.
An orchestra would be beyond my wildest dreams, but with a flutist, some actual work in the sequencer with the voices each on their own, and some more sample machines I guess I will be able to make it sound good.
Normally I do not really like to do things that aren't what they really are. I prefer the artwork to be sort of transparent with each layer visible in its own right. But with this I am "simulating" as I have dreamed this up and now need to have it in.
