Nice use of the samples. It's a nice little jazzy piece. I would suggest to bring down the volume on your synthetic bass just a tiny bit from 2:29 to 2:50, but other than that, this is a very nice piece.
A nice "jazzy" piece. You created a very cool vibe. The drum track was really cool, don't know if you added the echo or if it came like that but a great choice.
Great melody and well orchestrated. Only suggestion would be to pull back on some of the instrument volumes, they sometimes overpower each other.
