Nice composition, simple but effective, and the instrument choices work nicely for the forest vibe. I could see myself exploring a forest area in an RPG, so nice job 🙂 Mix wise I think the birdsong/ambience could be sat back a bit, maybe prominent for the opening bars and then let it fade into the background a bit, but I can accept it as the in-game FX track 😄 And the pad I feel could also drop back a little bit. My only compositional note really is that the middle section where that sequence of 8th notes drops out could have maybe continued it in a different voicing and more subtly, to keep the 8th note feel going? But what you did is fine ✌️
