I really like the beginning. The melody is really great! I don't like really 0:34 - 0:42 at all. It's because of the sample you used for the main melody. Feels too different when compared to the previous part in my opinion, and from 0:41 it's also definitely too sharp. From 0:42 onwards it sounds good though! The melody is awesome as well!

The fluent transition at 1:27 is perfect!

I like the whole 1:27 - 3:14. My only complaint would be that the melody might be a bit too repetitive, but I don't actually mind it that much. I really good!

3:14 - 4:00 has a really nice melody. After that, the sound becomes too harsh though, although it still has a good melody.

The ending is pretty good as well!

I liked this track! It was pretty good!
Overall I'd say 4,1/5
