Good work for putting this together in your down time.
Consider working on controlling the light a bit more, things like the window in the back of the rig, exposures thrown off by light coming in from the windshield, reflections and such. Some of it is easily handled by using improvised scrims to block out light that does not enhance the scenes or makes computer screens visible (or a bit of PP to get the monitor screen shots back). Keep an eye on errant cables and hoses that cross in front of equipment too, like the green hose in front of the LifePack control panel. Keep it tidy and visible.
Also, take some time to look at old Physio Control advertisements for some ideas (my batt chief was one of the first medics from Seattle used for their Lifepack ads back in the 70's). In most of the advertisement and training pictures they have the tech's faces visible.
