This is so beautiful. The first frame reminds me of the pictures of one of my favourite children's book "A Kitten Called Moonlight." It's kind of all fuzzy and it really sets the mood.
When I first saw it, I wasn't aware there was different frames, and it would change every time I clicked back on to the tab and that last one was terrifying. If this doesn't get an honourable mention or something, I'll be surprised.
Good luck!
