Good job on the trees. Much better. Side-note: maybe the building would look more imposing if the trees were scaled down a little.
The interior looks rather washed out now. Try dialing back the intensity of those downlights quite a bit, and let lightmass handle more of the flooding. Another thing that hits me is color temperature: the downlights would typically be somewhere above 6500 K, whereas the sunlight might be in the 5000 - 5500 K range (depending on the time of day, but based on the angle of the light coming in through the windows, it looks like the sun is closer to the horizon rather than zenith).
