Okay, I nicked Daphne's copy for a few minutes and looked again. You're right, it's not a flattering picture. I don't know if I'd say she's sneering, though, it looks a bit more like she's trying really hard not to pass gas in such a way as anyone would notice.

The bloke's near her but I can't tell if he's with her or not. It's not a good picture of him, either, he looks like maybe someone just hit him with a Confundus jinx, either that or like he got started on the celebratory toasts before he floo'd over.
