Since you only had one angle looking right out the door, that's the only one where you'd need to boost the light levels. Truth is that I'd probably use a 4K or 6K HMI for a soft side key light (softened how depends on the space), and 1.2K's bounced for fill, or maybe an Image 80 Kino. I may have used another 6K HMI outside the door for a soft kicker when he comes through the door. I'd also have tried to get the art department to break-up the white columns with some tall plants.
Or I would have scheduled that one angle for when the sun wasn't hitting the background so much. Since the far background had greens that didn't burn-out to white, it's really the mid ground that is too bright, so I wonder if flying some 20'x20' solids over it would have helped take down the brightness.
