Halfway there...
You've got a song started, but I don't think it's finished yet...
I'd make the snares and drums less repetitive (yea, it gets kinda annoying) but you've got something going on with the strings... All you need is some variance. Some change in the song. You need to slow the song down at parts and speed it back up, or completely change the beat and then bring it all together.
So far, you've got the bare outlines of a song in infancy.
