Example of Color Grading

These are 2 basic color changing examples. Let me know what you think.
One gives a wintery/artificial/sci fi look while the other goes for a bit more natural/greeny.
Thanks! Constructive criticism highly appreciated.

Great cinematic music. As for the color grading...

It all depends on the look you're going for, & what you previously alluded to, story genre. Perhaps this kind of footage is not the best example of video to test your color grading skills on. Why do I say that? Because the video has so many different subjects. Normally we're grading for; 1 an overall look, feel, temperature, mood, genre, etc, & 2 for specifics, like skin tones, foliage, sky, water, etc.

Since this video has such a mix it's impossible to say 1 of the 4 videos is "better" or more appealing. For me, I never really saw the foliage in the lush green I want from leaves. If you search here for Simon Wood's video about a B&B in Africa you're going to see some deep dark lush greens. Also, though we came close, I never really got the burnt orange brick color I was hoping for on the house. There is one brief instant in the raw footage, I think, where we see the hanging basket in a nice robust reddish rattan look. Having certain objects or subjects graded differently from the rest of the frame necessitates masking, & some guys duplicate the layer & use blend modes & all kinds of tricks. Generally, if you're going to have trees, you want them to look like trees, unless you're colorizing for a post apocalyptic dystopian future, or day for night, etc. Here with the camera going up & around & everywhere, we have to decide exactly which subject we're grading for.

If there's a grade you personally like for the specific kind of film you're aiming for, then use that one. Even after that decision you might still have to go in & help out the skins, sky or whatever, depending on the shot. You might also want to experiment with some various kinds of filters on the lens (ND, UV, etc), just to add to your repertoire of possibilities.
