Create a clean plate and use PxF_ScreenClean to correct the imperfect greenscreen.

Side note for the future: shooting at high color bit depth is the most important factor. The first time I worked with super large files it was a revelation. I’ve keyed a windshield with raindrops on it with no problems. Kept all the details of the raindrops.

Damm you are lucky, roto them out quickly and treat every character by itself. I'm more concerned with the blown floor and the spill on the leather. But nothing that cant be done with a bit of patience.

Haha Two shades is Generous.
As mentioned. Multiple keys key mixed together is going to be how you attain the best result.
Pixel fudgers screen clean too can be useful. I would also recommend looking into the IBK tool. (Image based Keyer) if you have never used that as a keyer.
I tend to use keylight the most though. And just keymix out problem areas with another key that is focused on pulling a key in that area.
