This suffers from the musician's quality of needing better vsti instrument's but that should never get in the way of getting in the way of a musician because it's ideas that motivate you. At it's core a pop song is supplied by a singer's personal melody , but as a classical stand point it needs more variation to keep the listener interested.
Personally I would use some slight reverb on the instrument's and make it loop properly, or make at least a proper ending for it.
What I love is the mood it create's. :-) A sense of enjoyment.
