I like it dude! All up to that point anything after the blue I didn't really like tbh

Would you mind telling us what distortion you used in serum? Because I usually go for zero-square or sin-fold

Don't: Allow them to change YOUR music because they want it their way.

Example:
*Producer 1 sends WIP to a friend and asks for feedback.*
Producer friend: "I don't really like that bass/synth you have there" <- Wait a minute. He gave an opinion on what he thinks to your synth/bass in your track. Just because he doesn't like it, it doesn't mean that everyone else will also share that opinion. You have to take it with a grain of salt. If YOU feel that you're getting across the right
- Theme
- Emotion
- Style
of your track. Then stick with it.

Honestly it's good to leave in some empty space.
That way your song will sound more dynamic and if there's too much empty space, you can take care of it by mastering properly to fill those gaps.
More layers like pads, extra leads or sound effects like white noise or other fx can always fill up the song.
I like to think of the song as a big bottle. All your instruments are big rocks that fill up the bottle nicely but there are a lot of gaps left in between.
These additional layers and effects are like sand that smoothly fills up those gaps and makes it a full bottle aka a full song.
That's how I see it =D
