The composition and orchestration of this very much sound like we're ready for a video game adventure! From the opening chords, to the A theme with its differently orchestrated variations, to the B section changing things up, the journey of the music hints at adventure around every corner. A story with a beginning, a middle, and then... 100 hours more of playtime.
The way you orchestrated the strings especially hits genre conventions and works to create the feel. Legato, staccato, and pizzicato all used appropriately to keep up the momentum and change up the texture. And despite the variety of chords and moving parts, harmonically it's very well put together with no awkward dissonances or holes. This sounds like it was made by someone who has spent more than a little time studying music theory.
I did find that for myself, the AI art initially killed the vibe and didn't set me up to expect music that's made by hand by someone who knows what they're doing. Usually I wouldn't have clicked on this. But I saw the discussion in the discord so I decided to give it a try.
