I like your melody stops around the 2 minute mark and you have the quick 32 note arps. Transitions nicely. Good sound selection.
The bass at 3:24. I somewhat agree you could switch up the rhythm and give it more swing. But it's not bad at all. Just preference really.

Good atmosphere and space. Sounds nice. I had no issues with the hats.

Sounds good. But as others have said, the bass is a little wide and muddies the mix. Get that tighter. There's too much on the sides, me thinks.

Mine aren't simply a single sine. I like to detune it a bit and give a small amount of frequencies around 100 Hz. but no further.

And I sidechain it to the kick all the time because i want to kick to have the power that low frequencies around 40-100 Hz give.

Something similar to this.

I use a Massive patch and use two sine waves. One that will hit around the 40-50hz range and another tuned up an octave to hit at the 100-150 range. But again, no more. This is good so smaller speakers still have bass.

-What is that pluck preset? Really enjoying that.
-What did you do at :40? That was a confusing transition. I hear it a bit on the chorus too. Are those glitch or reversed chords?
-Agreed with the others, the verbs a bit much. I'd suggest putting the reverb on a send and sidechaining it to the bass midi/audio so that the reverb only comes in after the midi/audio is finished.

Songs not bad, a little too much repetition of the same melody for me. But each their own.

A big thing I'd change though are the drums. They just lack life to me. They seem very bland and just filler.

How do you beta test sounds?

I did this today and it worked to give me a nice baseline to start with. I recommend.
