I want to address your issues individually.

Attached a picture- does this look normal? I know it's kinda hard to make out.
Definitely Orange Peel. And below is why......
It was getting pretty cold when I sprayed as well. Not a warm, dry environment.
There ya go. The smoothness of the paint is tied to how fast the moisture evaporates out of it, and cool, humid conditions can ****** drying times significantly. The Paint then lays there, and areas tend to coagulate. Then, when the surface does dry, it's "lumpy". The fact that you did Dusters is what probably saved you from getting Paint Runs outright. I would venture to state that you followed on Duster too close on the heels of another, and the combined moisture of multiple coats helped to create the Orange Peel.
What are your thoughts, gentlemen? Should I sand to take it down a bit?
(Apart from the orange peel/texture issue on bright scenes the screen looks terrific, btw!)
Well that advice has been given. And heeded hopefully.
As for the painting, after you do sand, apply a Duster, and let it dry for at least 2-3 hours before applying another. Also, after the surface has at least dried so a light touch of the finger leaves no mark (1 hr), than direct a Fan on the screen for the remaining 1-2 hours. And yes, you want to be certain the Paint is thinned enough, but all the same, make sure your Dusters and truly "Dusters" as the poor drying conditions will make thinner paint have more of a tendency to collect into sags and develop runs.
Under warmer, drier conditions, a Duster will dry in under 30-40 minutes, and under "Earl Schibe-like" heat and forced air....15-20 minutes.
But damp, Polar-like conditions are not conducive to obtaining a decent finish when all your doing is paint a Wall with ordinary Paint, let alone trying to get an almost perfectly smooth surface on which to project high resolution / high contrast imagery.
