First off, I'm a big fan of the whistle and the piano, it gives the whole track such a unique vibe. Like you're about to leave the city and go into the place you actually came here for. I definitely would change the sample on the brass that's playing the melody, because it seems to be a bit off from the rest of the instruments. Maybe you could try some marimbas or vibraphones, I think these would work perfectly. Overall there's a lot of potential in this one, and I do not mind the shorter length. It's mixed well.
