Darn tumblr, not letting me reblog your question; I apologize for filling your ask box. My first thought was a picture of you playing a tune on your lyre, but I am open to anything that you would like. Perhaps one of you and Sweetie Belle since she is such a big part of your life right now.
How about something lighthearted or silly?
If you can get permission (if you need it, I have no idea), I love this one picture from this Lyra.
Whatever you want, though. I’m not terribly good at this sort of thing.
