Nice job
This is pretty nice stuff... too bad you didn't have a better piano sound. It was a bit tinny, maybe you could mellow it down a bit if you make a new version.
This is a great song, and there are many many good things about it which other people have picked out. So, I will be the asshole and critique.
Some of the instruments were not together (mainly when you were "all together now". If this was intended, it was destracting. If it wasn't intended, it should be pretty easy to fix. The notes are right, just a bit off.
Maestro- I loved the entrance of the strings in form of a major chord, it was very beautiful. The drums seemed a bit lacking in punch, maybe have them louder, or have a bit more complicated beat as they progress?
Milkman, the drum beat was nice, I liked it. Simple, yet catchy. You may want to fatten them up a bit too though, the sounded thin (too trebleish).
I think it would be better if you scrapped the voices, but if you each had your own theme that you somehow portrayed in the song. Maybe Milkman's could be more electronic, and Maestro's could be more classical.
Don't get me wrong guys... this is a great piece of music. I think the ideas are all there, they just need to be developed and tweaked a bit more. Keep it up you two!
(for the record, I'm giving you guys 5/5 for this because I really want to see you get some recognization for this piece!)
