For a first time effort I like this a lot. I think it was a good idea not to use those puffy default clouds especially in that location ie. French Alps.
Unfortunately this clip is too short to allow for much criticism.
This short scene IMO lends itself to a method they use in movies a lot, you know the same take from different angles looped together... for example, start the way you did, then use an angle from about 10 o'clock or 2 o'clock, next an angle head on (12 o'clock) and finally an angle from 3 o'clock or 9 o'clock depending on where the sun is.
Not necessarily in that order of course -- just a suggestion. If you need advice with the positioning of the camera, I'm sure other members who have already made their own vids and perhaps some of the guys who spoil us with their great screenies will be able to help you.
The frame rate jerkiness is hardly noticeable. If you do wanna try to iron this out, for an experiment set your FPS to 'unlimited' in the sim's settings. A tip a friend gave me, it works wonders in my case as I have an inferior graphics card.
Now all I have to figure out is how you managed to clear those trees...
...does this aircraft have STOL capabilities Sir? 😁
