Overall, very good video. You have some very good scenes but I think you could improve the colour grade in several ways. What strikes me most is:
- The first thing that strikes me is that there is no uniform colour scheme throughout the video: we have scenes with too much red, others with too much blue, ...etc. Try to make all the scenes have the same colour scheme: make them look like they were recorded by the same camera at the same time.
- In general, the first scenes of the video have too much red (especially in lows and mids) and not enough green. That doesn't make them very attractive to the eye
- On the other hand, the details are important as for example in 2:11 where the water of the waterfall looks very artificial, between greenish / bluish.
On the other hand, I don't understand the change in the video from 2:21 onwards. What happened with the Madeira video, why those scenes without LUT applied and then with LUT applied?
I hope these comments will help you
