Nice bright vocal - very pop!
Snare has a nice snap to it.
Very clean, open mix.
...maybe a bit of alignment on the backing vocals for the final chorus... though, when they're sat back earlier in the song - they work... just become a bit distracting when they start to compete with the lead vocals for attention.
...drums feel a touch small... but it kinda works, as it keeps the mix feeling light and pop.
Overall I say, you captured the youthful, lightness and bounce of the track really well - I enjoyed the mix a lot 🙂
