I like the way the nature of the theme and the timbre of the instruments complement each other. The harmonic structure of the piece is fairly interesting, it isn't just ionian or aeolian. when I heard the piece, it gave me a jungly vibe before i looked at the tags, so good job on conveying your message, there. The only reason I didn't give it a full 5/5 was because I feel like there weren't enough tonal shifts - C seemed to be the tonal center throughout. Other than that, cool piece. Also, interesting ending on a V chord.
