"For the music, I'm assuming you mean instead of/in addition to the current music?"
The current music is okay. No problems with that.
But I was thinking that at some scenes, where you want to evoke a specific atmosphere (like a heartfelt conversation, or a party scene), you could use some music which feels like college comedies.
I dunno, but for example Blink182, Offspring and such remind me of these movies. (probably due to my age) Obviously these well known bands are a no go, but I think it is possible to find similar to these in tone.
When I was looking for free pictures for a tabletop RPG I did go through a mountain of "free for non commercial use" pictures to pick out ~30 I wanted. I think it took me about 20-25 hours to find those. So I understand that this would require lots of investment from your side.
I'd love to do even more body diversity, but I am somewhat limited by the engine I'm using.
I do miss curvy ladies from visual novels, but I understand the limitations you have :) This is still better than most of the VNs from this perspective though.
I'm so glad you liked the balance between characterisation and lewd scenes
For some reason this balance is not that common, even though I would think it makes sense?
Most games female protagonists are usually either well written but super innocent, or nonsense corruption games where the protagonist is irrational.
