Nice job, Moon river's embrace is a cool ethnic take, lookout for some playing sometimes it feels a tiny bit quantized and not has human but its a very small detail.
Same for the sun mountain, some of the strings melody feels a bit MIDI in terms of note choice and playing together and yes like most people mentionnned a bit of reverb would help.
nonetheless a nice take on the theme and the motif, I like what you did with it, its not being repeated every 5 secs theres is a lot of variety, good job
