Nice melody. I really like the drums you used and how you used them.

I agree with LexaHergon's statement that it is too difficult to distinguish the piano from the plucked string notes. They are playing around the same frequencies and their sounds get confused together. I think many people would also find the frequency overlap (/muddling) between the violin and piano to be bothersome, but I don't mind it.

I actually rather like the sound created by this track without a bass line, but some sort of bass presence would probably give it a nice, fuller sound, and appeal to a much wider audience.

I love how the piano and drums seem to work together perfectly! they kinda just HIT YA. XD but around the end of the track it feels a little jumbled. and the drum break at 0:52 seems a little bland, you could perhaps build that up with the music just before it more. but as this is your music, its completely up to you. but i like the track regardless.

I like the idea, the melody line, and harmony, but there are some things to fix.
The plucked string sound, and the piano crash into each other, and it's difficult to distinguish both sounds sometimes, maybe a darker piano sound and panning could fix that.
A simple bass line, better drums sounds and hi-hat are a "must" to improve this song.
I'm not sure about the end, but it's just a matter of taste, do not take me too serious.
