I'm not sure how to get the more photorealism you guys are... still looks a little cartoony.

This is really good. Just amazing!

I'm wondering what prompt did you use to get her to wear that. Wow.

I tried inpainting in Automatic1111 for the first time to try to improve the realism. Personally I'm not into wetlook, but I just had to see if it would work so that I could recommend to you to try it. It has pretty high requirements on the graphics card.

I made 4 passes, generating at 1024x1024 (I cannot handle 2048x2048).

1. Very low denoising strength like 0.01, mask on her face, restore face option - to improve her face.
2. Mask on her hair, low denoising strength like 0.3, with prompts to try to improve her hair.
3. Mask on her torso, low denoising strength, using a Lora that I trained on sweaty women to get her to shine.
4. Again the same thing with the mask on her legs.

I did not touch her arms or hands. Her arms looked really good.

Then I upscaled to 2048x2048. It loses some quality from the original, but it adds some realism. I made her a bit sweaty and tan and less wet. I could share more details if you are interested.

The hair is very difficult. It looks more sticky than wet. I might be interested in training a model to improve results. I don't have any wetlook images in my collection though.

I think the prompt for the clothes was something like (tight sheer blue long-sleeved bodysuit), though the "sheer" may have had it's own weight.

I like your upgrade!

For fun, I wanted to play with her hair a bit more.

First I applied some suds on her legs using a lora model which I trained. This is unrelated to her hair, I just thought it would be fun.

Then I made her hair dry. It was too difficult to work with wet. It become really silky looking. I extended her hair to reach the bottom of her breasts.

Then I tried to make her hair wet again. It was very difficult. It just looked like a wet mop, so I decided just to make it a little wet.

Then I decided to put some soapy suds in her hair.

I did not upscale any of the images this time. They are 1024x1024.
