Wow, I just love these short, jazzy tunes! The drama at the beginning was good, but I was a bit confused by the pacing shortly after. This is going to be nit-picky. I thought you were going for a classic Forte-piano and then rapid crescendo during the first 5 seconds, but the crescendo never really came. This made the transition into the sneaky-sounding piano at :06 fall flat IMO. The first chord sort of brings this energy into the piece that is quickly reset and made more mellow. I just thought it threw the listener off a bit to have a dramatic intro perhaps predicting a fast-paced piece, while the rest of the piece progressed rather slowly. That said, the part at :06 and beyond is moody, charming, full-textured, smooth-flowing, and generally has all of the ideal compositional values I look for in a piece. I admire your sense of rhythm and harmony. It's a very catchy track. You should go for a full-length track sometime where you can really space out your ideas. :06 to 1:28 would make a great intro for a 5-6 minute track. I know that this piece already feels relatively conclusive as it is (I see you used the classic tonic octave-jump), but more development and structuring is necessary for this to be a truly complete piece IMO. Like I said, though, this review is extremely nit-picky. Your compositional skills are already rather good, and the mix seemed pretty tight as well. Keep at it, man! ;D
