Enjoyed these a lot, especially the playfulness of the first track. Definitely can imagine dancing wood sprites and fey creatures frolicking in the woods.
One suggestion I have is to adjust the velocities of your piano and brass notes more individually, or even just randomize them. It would help shape the lines, add realism, and have them feel less heavy/same-y.
Love the compositional ideas you had, and good instrument choices for each section. Good stuff!
