I’d say some of your overlays were a little off. Like the desk with the secretary you can see her feet popping out. The MC would sometimes end up behind the overlay.
Maybe change your background characters outfits from the default outfits as well as their features. I know it’s a lot of work but it’ll be worth it as your readers do notice those things.
Sometimes when your characters are exiting they get bigger. Maybe spot direct them as they exit.
Overall though I really enjoyed it and I like the plot and I don’t think I’ve read a plot like that before. And that boss is a sl*t 
PS,
I know some of my characters are popping up on screen and maybe some layering is off (I think that’s a glitch) just an fyi
