Mike,
Interesting tune. Very suitable for kids show. Rich arrangement, yet listens well.
I was trying to come up with meaningful suggestion and looked above. I could not of said it better than Steve. Fades on strings are a bit aggressive. I listened as whole, then couple of separate parts... I see that it might be tricky to maintain a single instruments, especially on articulation parts around 2:40. Perhaps using 2 separate string instruments would help? Thank you for sharing.

Misha.
