Also, Wilde was a hedonist and I'd bet money that part of Snape's repressed nature is due to his Puritanical streak. The drawing catches that perfectly. What's more, Snape's considered ugly, and Oscar generally didn't waste his time on chance encounters with ugly men.

So, yes, it's likely that Wilde would find Snape distasteful and pathetic, and he'd probably drive Snape up a wall.

A marvelous idea, and a marvelous drawing to go with it.
