Okay, this is not going to be knock on you if that's how this post is going to look like to you when it's done, but..
I just had a listen and I have a couple of questions; Why are you learning this song (in particular)? Depending on your answer; how important is it for you to know the theoretical side of all the stuff that's going on? Especially if you're learning it by GuitarPro, rather than (for example) by ear? How useful is learning this song going to be when you want to learn other songs later?
Learning stuff with GuitarPro is a great way to quickly be able to play something, as reading tabs is (for most people) remarkably easier than reading sheet music. I can read tabs with relative ease and play through a lot of stuff I've never even played before, simply because reading tabs is so easy. But doing that, I'm not really learning anything, other than a 'trick' (place finger here, then there) as long as you're not in some way conscious about what you're playing. Reading sheet music inherently makes you more conscious of what it is you're doing (E gets followed by G, that's a minor third. Against an A minor chord, that means I'm playing the fifth, then the flat seventh). I'm not saying one is better than the other (well, kind of?), but I
am saying that all the stuff is in the music itself, in order to learn what's going on, you're going to have to be conscious of what's happening. You can learn a lot from practicing songs wit GuitarPro as well and in some cases it's definitely far easier and more convenient to do it that way.
I know someone who learns everything by GuitarPro, to the point he has no idea what it is he's playing (as in, what notes he's hitting) and he barely knows where the notes are on the guitar. He can read tabs well enough to study something and also play along to the original, but then he'll stick by what he's learned (wrongly) from the tab that had mistakes; he's doesn't hear that he's actually playing some wrong notes here and there. He also might not realise that the song contains a repeating chord progression, because the guitar part changes in the second verse (for example), meaning that to him it's something completely different while musically it isn't. This is what you (ideally) want to avoid; be conscious of what you're doing and make music, not perform a trick.
Regarding the picking, using hybrid picking and sweeps is something that I've seen pop up a lot more often lately, among bands and groups that make similar music to this. There's a lot of Instagram guitarists copying this same thing as well, so I guess we'll only see more of this sort of thing in the future. Thing with that particular technique is that its uses are relatively limited unless you apply it to your playing in some way. I use my middle and ring finger a lot, usually when playing chords (pick between thumb and pointer, middle, ring and even pinky for three other strings), but it took a lot of conscious practice in order to get that in my routine for example.
Learning songs (and I mean full songs, not just main riffs!!) is a great idea, but this track you're practicing is not really a standard song, so learning this might in fact not be all that different from doing technique exercises.. limited application in other musical situations. And it's not as if someone would ask you to play this song (nor would it really be possible) when sitting around a campfire and you get handed a guitar. This doesn't mean I'm discouraging you! By all means, if you want to learn to play this one, go ahead and do so. I can imagine it's a fun challenge.
So in this track I'm not hearing any really uncommon stuff harmonically or melodically. The harmonies are quite simple and nowhere in the song did I get the idea that there's anything strange going on, though it might seem flashy with the flurries of notes and rhythms going on. I'm hearing like a main 'theme' sort of thing that consist of two chords a major third apart, then there's a four bar repeating chord progression and these two sections repeat and it ends with a new four-bar chord progression. I'm not going to figure out all the chords, but you should be able to if you have the tab (or do it by ear!), but also rather than going note for note, figuring out the bigger picture, the structure of the song) is a really good way to learn how the music is constructed. Good luck
