This is my first post here, and I can feel good for actually doing something creative... These are just my thoughts on your work.
It sounds less like a string piece and more like a solo violin with random background pop music that happens to contain string instruments. The violin part is okay, but it might be better without the drum set and with more real harmony. As it is it sounds like a long commercial jingle. It needs another part to harmonize with, or else it sounds like a substitute for the human voice singing about Goldfish, you know they're made with real cheese, even though they look like fishies.
I don't want to sound nasty, I just think there should be less drums and more harmony...
