This looks absolutely magical. I'm honestly not a huge fan of shipping anypony, be it a main character or background, but this is just amazing. I love the panter-ish shading style to it, and that lamppost looks great. Lyra's and BonBon's posing and expressions look simply adorable. Add the touch of snow and it just makes it complete.
I mean, they look like they're coming back from their date, much more comfortable with eachother and sharing a scarf. Just simply adorable.
