Reminds me of the FUS RO DAH theme from Skyrim. I like your choice of percussion as it nicely complements the forest aesthetic with some foliage-like sounds but I think it gets overbearing about a minute in.
I like the concept of how the music fades in and out to reveal the birds chirping in the background but the tone of a quiet forest and this adventurous theme are at odds with eachother and do not work well together.
This is most evident 3 minutes in, where there's some ominous stuff going on but you can still hear the birds cutting through, taking away from the drama that the orchestra is trying to capture.
