Good.
This is a nice Song.
You made a gently exciting, and satisfying piece using, syth melody, decent rhythm.
All very good, nice a peaceful, relaxing, maybe suitable for a space Flash game/movie.
However at 0.41 seconds a distorted effect occurred i guess you added thas as an effect? Whatever the reason i did think that it ruined it a bit, the song went from clean and exciting, to annoying, still with a good rhythm just very disappointing.
I also would think it would be nice to add in a louder more predominant beat and add a phaser/flanger effect there just ideas.
Apart from the end i though it was Good.
Keep the Good Work up.
