Gorgeous! Their lazy, lusty long sexual adventure goes so well with the mood of a sultry summer night. I love how they end up in the lake; it's better than Quidditch, it's like they're expressing the height and depth of their love by taking it from the skies down to the water. Add in a roll in the hay - er, grass - and a basking on the lake shore and they've shown how very much they're part of Hogwarts. On this moonlit midsummer evening, they become part of nature, because you've made them as lush and normal and natural as the rich heavy evening itself.
The drawings are beyond excellent! So romantic, so much beauty, they really embody the story and the mood. The pen and ink technique captures the feeling of rumpled sheets after a good romp in them - or above them, in the current case!
