I like the apprehensive mood at the beginning. The synths blend well together, and enhance the mood of the piece well despite being a bit generic. The mix is pretty clean, although I think the snare could use a little more compression - I just wanted it to some more crisp and distinct. The piece is missing some strong melodic content, although you clearly have a good sense of harmony. It also gets a little repetitive after a while, and could use a little more shape and contrast, especially with regards to the main riffs. The loop is smooth, though, and the piece is quite catchy. Solid work!
