I must agree..
with everything TeHLoY wrote down there. Still, a very sweet melody, really, keep it up.
This song is pretty good, but I can tell the melodies are repeating a bit too much.
Also, this isn't really long enough to be a song. Its more of a loop, if you can make it do so.
Also, I find the synths a bit piercing to the ears, its a bit too high pitch.
You should try to make the song longer, add some melodies and such...
Still, its a pretty good try!
