Excellent work - not often that people are willing to re-edit to try and get a better result, so bonus points for perseverance, and, because of that approach, your video is getting better all the time...
Still a way to go though... let me try and explain.
First off, let's fix an easy one - lose the novelty pound-shop transitions. Watch any BBC or other broadcast quality documentary, and I guarantee you will not see a single one of those ! Outside of trendy pop video nonsense, there are only 3 types of transitions that anyone serious actually uses - the straight cut (or no transition at all), the fade in/out and the cross-dissolve. All others should go in the bin because they instantly reveal your amateur status if you choose them
OK, now, still a couple of shots shouldn't be there at all; the slow rise whilst looking out to sea, complete with its sudden jerk toward the end), and then weirdly fast180 degree pan and then inexplicably back again 3 seconds later starting at about a minute in. Now, of course I do appreciate you were here to learn to fly as well as making video, so these moves are eminently forgivable but that is no reason to put them in your public videos !

Nothing wrong with that slow rise per se, except that what we are looking at is (forgive me) possibly the dullest example of sea and sky we have available to these shores !

That's not your fault of course, but again, you don't have to show it unless something good or visually interesting happens ! Other shots are good, and only warrant criticism for their lack of variation and the amount of repetition going on (see dull location) but you have minimised this by keeping the video short, so that's all to the good.
Let's address the music quickly now. Good points - you have chosen something that very much fits the feel of the location and weather on the day, doesn't attract too much attention to itself whilst not being musically uninteresting, and is consistent throughout in terms of equal loudness, which are all good things in terms of enhancing viewing experience. But your video is not doing the same sort of transitions that the music is. You almost hard cut (or at least VERY short fade) the video in at the start as the music fades in over a much longer period, for example. That is a clear indicator that the footage (and especially that first shot) should fade in at a similar speed as well. In fact the slow, evolving chordal shifts throughout the music virtually dictate that all the clips in this should be fading or crossfading to match it - that way it will feel less 'plonked on' and less like music and video are disparate elements. In later videos, when you've had a bit more XP we can go on to learn about selecting shots relating to the melodic and chordal shifts within the music, and timing cuts to the pulse within it (if one exists) but let's not worry about everything all at once hey ?!
And now we can offer a quick word or 2 about (colour) grading... am I right in assuming this hasn't had any ?
Don't know what color profile you filmed this in, but we are lacking sharpness, saturation, and we need a bit of levels correction. There are more than enough videos online that show you that, so I probably don't need to go into it further here.
So, lastly, Having eliminated most of the flight erraticism, the main thing that is opposing you now is that the location itself is actually quite dull, and with not much in the way of variation or wildly interesting things to see, which makes us have to work a lot harder as pilots to try and show the location in as many interesting and varied ways as possible and thereby produce an interesting video out of a dull location. For that reason I would use this video (which I wouldn't publish at all) as my 'scout flight' from which to plan some proper intentional shots next time you fly this location. Looking at your footage, we can plan exactly which shots we need next time. To my eyes these would include:
1. Long, fast, low tracking shot about 2m above wave level following the curve of the shoreline and moving directly along the breakers at 60 FPS so you can slow it down by half later in your 30 FPS project...
2. Slower but equally low tracking shot over the part where the sandy beach meets rocks and vegetation.
3. A travelling side-pan or back-drift shot along the cliff face, pointing obliquely at it.
4. A high pass over the beach with camera 90 degrees down, probably over the shoreline, and again at 60 FPS.
5. A VERY slow pan round from the expanse of the sea to the coastal village, possibly combined with a slow rise....
6. Following on from that a medium speed, medium height travelling shot over the village following the cliff-line curves, but with focus on the buildings and lush green vegetation.
7. A low(ish) fast travelling shot in from the sea towards the cliffs and rising to reveal the village
And then some B-roll stuff to cut into all that to further make it interesting.
1. Static camera parked on the beach filming the birds nice and close, both on the ground, and flying close to it
2. Locked off static shots of say wind blowing grasses / reeds or bits of slowed down ocean spray (if you could find any!)
3. 5 minutes of location soundtrack recorded stationary on the beach, to use in conjunction with music.
4. Perhaps film yourself (hand-held) walking a sandy path to the beach, or down some perilous steps - you know, to 'tell the story' of the day a bit more...
And when planned shots go wrong (as they inevitably will sometimes), and you find yourself inadvertently having to climb suddenly, or jerkily move to avoid something, just go back and start that shot again, and only use the one that worked in the final edit !
And that's probably more than enough whittering on from me today, so I will pause here until your next iteration, should you want to rise to the challenge !
