You do a great job of using the instruments realistically. For example, the violin stabs at 0:25 crescendo and decrescendo at a natural pace. From what I can tell too is that you recorded yourself playing this (not easy to do, especially for short, staccato notes).
I think you really did capture that forest feeling by having short motifs of various instruments that are contrasted by the short up/downs of the violin.
Another aspect I want to point it is the way you arranged the volume of the instruments. The lead melodies are heard distinctively louder than the rest, and you follow an order of importance from then on.
Fantastic work, Sepharite. Can't wait to hear more from you!
