I loved so many things about this story. The image of an angry Severus with wings and white robes was hilarious. Your little 'cloud people' were a very original way of showing people back on earth.
And of course the scene where they're both drunk was incredibly hot, and the follow-up guilty!Severus was very IC.
The way you played the two little worlds was very creative. I felt so bad for Harry when it seemed like his children would cease to exist, but you handled that beautifully as well as gave some UST. When they finally did come together it was like taking a breath.
