Listening is key. And for melody and phrasing, and trading melodies between sections of the orchestra, and playing the same thing at different dynamic levels, and repeating something the right amount of times and then doing something else for a while, and then still something else, etc, I blatantly suggest Beethoven's violin concerto. It's all in there. It's like a textbook.
And Rick Beato has some good stuff about music theory, film music etc on youtube.
And for a fantasy village/city theme that's about 1:30 long, here's an example I like:

It's just a four-part theme repeated twice, once on flute with swelling chords and once on violin with more percussion and harp. So it's an AA structure but the As have different instrumentation. One and a half minutes isn't long.
Regarding your composition, Mattias is right. The flute is meandering. Try starting with a simple bit of melody, just 5-10 notes or so. Then take that and repeat with a variation. Then find some sort of closure. Like in the Drakensang example. Try to do a call-and-response thing with pauses in between. Make a motif out of a call and response thing, then make a theme melody out of several motifs or phrases or whatever it's called. Start with small bits and combine them and vary them, do some call and response, and build a full melody that stands on its own like that. Like using lego bricks, really. A kind of modular approach. And find out what phrasing is. Something like, play a snippet, pause, play the next thing. Don't ramble. Then try playing with dynamics - play the same thing quietly, then loudly. Or have a loud A part, a quiet B part, then return to the A.
For chords, I suggest looking up some standard chord progressions and just starting with those. There is such a thing as a standard harmonic progression. There's probably thousands of pop songs that use the same three or four chords. That's because they work. Same in film music.
Alternatively you can start with a melody and then let the bass or cello or strings or harp do something that sounds good, without thinking in chords, and create harmony that way.
For a technical tip, your music would be more listenable with reverb on there. Just take a free reverb plugin and choose a standard hall or stage reverb, and it'll sound ten times nicer. For mixing, in your first example the harp is overpowering the flute (too loud). Finally, there are some pretty loud notes on the flute in the second take, you might consider a compressor and set it to a really soft setting like 3 db of gain reduction with a "soft knee". Just as an idea, if you ever feel like playing with those things.
The phrasing and pause and call-response things would be good to consider next, I think.
Edit.
If this wasn't enough, here is an example of structure that I personally like: the Pippi Longstockings theme. Notice how there's a lot of repetition in the melody, but also distinct parts. There is a short intro that lasts 12 seconds, then it goes to the A part until 0:33, then to the B part. At 0:44, it goes back to the A part for a bit, then at 0:57 it goes off to some completely different place in a C part, for a very pretty effect. Notice the long pause before that. Also notice the bog-standard chord progression in the left hand.
