Hi Kakku,
You do wonderful synth work. Older tune huh? It has a distinct 80's feel to it which I like. It isn't coming across as loud as some of the pop tunes I've heard in this genre...that's probably the only thing I would change personally. I might make the bass a little more powerful and put the whole mix up a little louder. It was still plenty loud when I pulled up my volume control though, but I had to take it up some.
