Not OP, but I agree with what you said, so I did it. A single img2img to clean up the whole thing in general but keeping the anime style since I assume that was intentional. Then some iteration on the hands and one on the hat to make it less ridiculous.

Then did a second img2img to make a photorealistic version.

Some notes of my own for OP: I don't know what you're using to generate, but your results don't seem great. Here are my first ten, totally unmodified results for "blonde steampunk girl at beach in bikini, anime style", and here are my first ten for the same thing, but "photorealistic". Get a model that looks good at https://civitai.com/ and read some of the prompts people use there. Also, AI still gets hands wrong a lot of the time. Especially if they're holding something like a gun. But it can be pretty good at faces and figures.
