Nice
I enjoyed listening to this piece of music, you did a good job of the whole jazzy thing :D
the only thing i can comment on really is that it takes a while to get into the melodies and each melody isn't connected to the next one very strongly - also in the last section, the harmonies don't quite work, but maybe you intended that ;)
Overall, nice song but could do with a bit of improving. Still love it though! Bring out the parts which you find catchy and it could be a winner!
