Hmm....
Well this is interesting. First when the intro is finished it kinda mashes together. Im not saying i didnt like it, but they seemed like they were fighting more than they were in harmony. The background and the snths i mean. The background needs a different preset because it doesnt complement the lead. The first background seemed like a chiptune, and considering that ur lead is an odd one it needs to complement it. Like soul eater, if you seen the anime. Sous need to match soul wavelengths when they become a Meister and weapon set. The background and lead needs to match up in some form to become a song. Also the background dint seem to have a set of match chords. Can you try to fix that because it made me almost say no to the song. But despite all that im writing here thats only part of the song. The scat part was epic. KEEP IT! Also try adding a scat sample inside of your song as you play it for it to actually be an obvious tribute to John Scatman(Rest In Peace). Overall its good, but needs some minor Tweaking.
