Frogs are a little too loud and flat, though I think the idea of doing a frog chorus is cool and on point for the theme.
Composition is good and it creates a nice vibe. I think just mixing the elements in space and getting a better handle on spatial mixing would help. L/R is augmented by near/far, which is largely moderated by stereo width, stereo timing to the ears, and wetter reverb with lower delay for far sounds (vice versa for near).
