So, overall, your music is not bad at all, so i'll give you 2.5 stars.
Now, this is what i'm think about it :
-The first instrument is really nice, but the second comes too hard, and, its "break" the ambience you made the first seconds.
- the drum has too much kick for me, and is not really so rythmic, may be you should remove some kick, and add some snare ;)
that's it for me ;)
(Sorry if im speaking bad, im french ;) )
