I don't need to mention anything about the quality of the piano, however the way you added everything around the piano had me going for the whole piece. There are some things that need to be stitched up that other people have already mentioned so I won't bother. Except the birds, I don't understand the birds chirping... oh wait. After hearing the WUBWUBWUBS it makes sense now.
With all of that aside, what program did you use? Everything sounds really good and clean. All of the sounds are crisp and give my ears all sorts of good feelings. I'm blown away by everything that's playing in my ears.
Live long and prosper fellow earthling!
