This is fabulous!

The saturation works wonderfully; I can almost feel the sun shining through my screen.

I agree with other commenters - POC Hermione is lovely, and I really like how you've shown her blushing in so many of the frames.

I adore Pansy's face, especially in the frame where Hermione's applying the sunscreen. Just lovely!

My favourite part, though, is the hands! So many dainty fingers!
