I am no expert on filming but certainly looks very nice, slow movements, no jerky flying. All good, I am sure it will get better the more footage you collate and add, edit further.
Nice footage.
Which program are you using ?
I just started editing in Final Cut Pro and knowing how difficult editing is, makes this movie even more impressive .
But what's more important it gives you an idea what to film and how it can be used in a movie.
