Exploration Themes: These are very calm themes with a serene ambient forest vibe. I love the combination of strings, flute, and piano - you nailed the Ori vibes!
Combat Theme: I like the dynamic transition from the exploration themes into this more upbeat combat theme! Use of cymbals helps energize the soothing gentle exploration themes. I think you have really good ideas with more rhythmically moving string parts with soaring melodies in the horns and winds. Your strings are very forward and while variation would also be helpful, I think simply lowering their volume and bringing the soaring melodies forward would give us a better sense of what you want the listener to focus on during this epic battle scene! Overall this was very pleasant to listen to! Good job and thank you for sharing!
