This was the original set from 2019 - I wouldn't say it's particularly bad, but I have done some things differently with the rework.
The main reason why I wanted to give this set another shot was that I was not satisfied with the skin retouching... both the color is off and it's a bit spotty as well. I have improved my frequency separation skills since I believe.
I have also used some sharpening that I haven't done before and stayed closer to the original colors, didn't add a pinkish tint. I used to experiment with that kind of stuff, but I am more of a purist nowadays.
My camera and lights also had limitations back than, I was using a crop frame Canon 700D I believe - there is not much I can do about this now, the pictures are never going to be as sharp as I could make them today.

It's really easy to do something like this at home if you have a bathtub or a kiddie pool. Basically one bottle of milk is enough to tint the water to this level of transparency. I think this is the sweetspot, if you add more, the water is going to be completely opaque and you loose the ethereal details of the bodyparts and hair falling under the surface.
I've used one light source for this, I am not sure if it was a speedlight or a continous light, but I know it was not good :D
