My home state being Washington and hiking and camping through its many forests, this description is beautiful and reminds me of the things I love about the forest. Many times I’ve bent down grabbing moss, smashing it right into my nose, deeply inhaling its fresh green scent.
A current discussion is returns or indenting. A return only uses one character, I would suggest adding a few returns (enter) to break this all up, which is easier on the eyes and gives your piece more power.
Lovely feel to it, a cautious forward movement for the character. Some run-on or just long sentences throughout. Some could be split and some feel like they could just use a dash or ellipses to set off the last bit, such as the line about the musk of the under forest.
