I absolutely love that little intro! I find it really hard to get the intro right in a song, I believe its a very important part of music. After all its the first thing the listener is going to hear and what their initial judgement is going to be of. That simplistic intro just really fit the rest of the song and is a very good start to let people know generally what the song is like in the first 10 seconds.
I feel like a bit more could be added to the drop, maybe something I like to call an 'overlead' which is basically an extra dominating lead instrument over the top of your other melodies, usually a relatively high pitched instrument to add some more depth, creating a more three dimensional sound. I actually found it hard to find a lot of things I didn't like about this so good work!
All the melodies flow well together and sound very pleasing. I like how you have different layers of tone in the first part but haven't overdone the bass or anything like a lot of new artists do. The drums of the that kick in sound perfect for the genre too. One thing I hope you don't do with the full version is if you have multiple choruses, don't make them exactly the same. Alter the second one a bit, add some variation, it always makes the music sound like a bit more love has gone into it.
Anyway, good work as a whole, Looking forward to the full release!
