Some help with a circuit I'm working on...hopefully

Hello all,

Long time, no post. Hope everyone is well. I'm sure hoping one of you brilliant minds can assist or critique an analog circuit I'm working on.
This circuit will scale the NEGATIVE dc voltage (ground referenced) of my plasma cutter, down to a usable ADC level. I've been simulating it
with the Falstad circuit simulator and it seems to work, but I would much rather have a second, third, fourth, etc. opinion on it. If you would like,
I can post the Falstad file in a code block as well.

Thank you all for your continued help in my crazy projects,
Chris
