Rather than disgusting, it's possible Winda meant more off-putting (like Blastaar put it) or unsettling even? In my opinion, it does have that sort of visual effect towards the end, it might even be from the fact it's all white. No clue. Again, all a personal feel, it was my jam up until it wasn't, ya dig?
Honestly, the idea of a couple putting body paint or makeup on for each other is a really cute one. There should be some cosplaying manga out there that revolves around the concept of just getting ready for each convention/whatever.
You're welcome, artists.
