This sounds like a trailer for an open world game! 

I think the mix and vibe are great! The last minute is definitely the best when the lower strings and voices come in.

The song structure of builds without a proper "drop" makes me want one! Gimme a soaring string crescendo with synths arpeggios to sell the idea of artificial life in the forest!

I think another section where the melody is traded between timbres/ instruments would help the pacing.

You nailed the theme though, on an epic scale!

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.

This is a really great forest theme as it captures the beautiful and wondrous parts of a forest, but also the mysterious and ominous parts. Your marching percussion makes me think that I am on an expedition traveling through the forest in your story. I really love the soft swells of the strings throughout - this compositional technique feels the most “forest-y” to me. I love that you set up a harmonic pattern, but then keep breaking it - that is where the mystery and ominous feeling comes from mostly I think. The bass growls and the field recording ambience also help immerse me in your jungle and makes me imagine being surrounded by wildlife. Great work and thank you for sharing!

Nice BGM! I could see it fitting right in with a forest scene in a game! I really like the percussion, but they sometimes felt a bit overpowering, covering up some of the other beautiful details you had going on in the music. Also, the percussion's reverb sometimes didn't feel consistent with the other instruments. The percussion has a powerful, echoey sound that conveys a large space, which sometimes clashed with the dryer sound of some of the other instruments. I think making the reverb and such more consistent throughout the music would make this even better. Loved listening to it, great job!
