You're gettin there. First off, you gotta start mastering stuff. You're piano is very clicky, try lowering the high end a bit. You're bass is way too heavy for the light feeling presented by the piano and is kind of bland. Try throwing some patterns at it rather than just long held notes. Go EQ it and lower everything past the mid-low frequencies. For your wind instrument in the background, try making it chords instead of single notes. Also, try adding some ambient style drums or something to add some depth. maybe a woodblock with a reeverb and a delay or something along those lines. You have a pretty basic idea here, and it's not bad. its just rough around the edges.
