I'll try to write something constructive
It's loud, i loaded it into flstudio to check the db levels, it goes over the digital 0 db. You should never go over the 0. Use a compressor or something to keep the song within that limit
Also, you should think about panning the instruments, it's something you'll eventually end up doing as you compose more music and it improves the quality and pleasantness of the song greatly so i suggest you check that out as soon as you can
Other than that it's good, the synth in the beginning reminds me of the Halloween movie theme.
