You've got a way of the Elfman about you! There's joy and wonder in your stuff but there's always an underlying darkness and a hint of menace. The orchestration is great, I love your voicing and the subtle dissonances in the back ground. The little china bell thing is a cheeky little touch, that made me smile;
"My milkshake brings all the boys to the yard,
And they're like, 'Ting' It's better than yours..."
I wouldn't know what to do with a timpani, but if I was to try, this would be what I'd like it to sound like so you may have just inspired me to use one... Nice with the MIDI toy too! That thing looks fun. You're on my favourites!
