Here's my offering for
nextgendarkfest. I'm really happy with this pic still, and I drew it months ago :)
My idea was that Harry has a portrait of Snape in his study -- in addition to the one at Hogwarts. Lily Luna and Snape developed a painfully romantic relationship over the years... and in this scene I imagined Lily Luna was going off to Wizard College or whatever and this would be her last night with Snape. I like to think she about to expose herself to him for the first time...
