Thanks everyone!

I think what I've done will keep dust out as well as a commercial cross-draft spray booth but the 2 differences are that a commercial booth will have an exhaust filter wall and better lighting.
If my stall were just a couple of feet longer, it would have been more feasible for me to have done a wood temporary exhaust wall and put it a couple of feet in front of the window with the exhaust fans. I thought about that but opted to try the USC spray masking on the fans instead. For side lighting, I'm just going to have to use portable lights like I already said.

Thanks for all the compliments everyone. My objective here was for sharing what I did so others might get ideas of things to do that fit their situation.
