Thank you for the detailed feedback! Yeah, you aren't the first one saying the opening reminds you on Pirates of the Caribbean, haha. In fact, Hans Zimmer used a very mainstream medieval melody for his masterpiece, so some similarities are recognizable.
The regular switches between major and minor (relatively low held on this piece) is something I usually do and I guess that's just my style. I like to provide the listener many different feelings during the listen, so do I enjoy myself these switches.
The chord-rythm was played by the actual acoustic guitar. I wanted the guitar to be a secondary instrument (background), since it's a bit more modern. On the other hand dispensing with it gave me the feeling something important was missing. The Lute serves as some kind of leading instrument, the played tremolo articulations would serve well for the real medieval feeling of the soundtrack.

Thanks again for the neet feedback and criticism!

Thank you for the feedback! Could you tell me what you mean by foices? I don't really understand.
