Your choice of instruments and harmony was absolutely wonderful, and very fitting for the theme of this jam!
My only critique is that the bass instruments felt a little overpowering at times, especially in that second section. It might help to either cut a bit of mid frequencies on those instruments for more clarity, or reduce the volume altogether so that the piano and higher register strings could push through the mix a little better, IMO.
Thank you for sharing this, and keep up the great work :)
