FIrst off, overall the track sounds good and is interesting to listen to, good job! Something that I find is one of the most useful tools when sequencing/programming is the ability to control velocity. From what I can hear most of the instruments are just being played at one velocity which makes them sound a bit mechanical, so I'd just maybe go through and change some velocities around- eg. higher velocity for accented notes, and lower velocity for non accented notes.

The string vst has a really nice sound to it, and I can hear that there are accents in there and you're aware of that kind of thing. Anyway hope that advice helps at all. Once again good job!
