Something more unique on OCR. And it's from Pokemon Snap. I'm looking forward to this.
It took way too long for the intruments to kick in. Either cut the intro significantly or introduce more instruments earlier. I would stick with the latter option.
As for the instruments, they're mostly fine, but I want to wait for the final mix before commenting further.
Also, it's easy to tell the bird sounds were from a looping pre-made sample, since I heard the same chirp at least five times. Their has to be a million other bird sounds out there, so search for more unique samples to add to what you already have (or you could record it yourself). Lower the prominence of the nature sounds as the instruments kick in, since they tend to overtake the instruments.
