Quite lovely.
Intro - triumphant and staight to the point, could be used when entering/loading the game. The flute pedal tone sounds cool imo.
Main theme - sounds like something for a strategic game, I like its vibe! On the other hand, I'd suggest making the drums a little bit louder, that would definitely upgrade the track and give it some more charm. As for the main leitmotif, it is catchy and memorable, so good job with that.
Ending - sounds like closure, so you did that well. The main melody's reprise sounds nostalgic, like we've went through a complete journey and have reached a satisfying final, it felt nice.
Overall: melodies are cool, ideas seem nice, yet mixing and balancing the sounds would elevate your music even higher. Good job!
