Man, these look great!
And BTW, the sky is red in that one shot because it was filmed at a different time. In the days before digital color grading, you could only shoot sunset scenes at sunset, and thus the lighting is constantly changing. Compound that with the fact that there's multiple takes, coverage, and the scenes weren't necessarily filmed in chronological order. Thus, in the final cut, we may hypothetically go from a shot filmed at 6 PM to a shot filmed at 6:30 to a shot filmed at 5:45, and the lighting will thus be inconsistent, even with the tweaks that could be made with photochemical color timing.
