You're right that it's not Lestat - it brings to MY mind the images Clyde Caldwell did for the old TSR Ravenloft setting - the colors aren't the same, the background is plainer, but the poses and the girl look a LOT like Strahd Von Zarovich and his victim (though in the Caldwell painting I THINK she was blonde and wearing a filmy, see-through gown...)... On a more technical note, you might want to rotate his right hand up a little, or move her legs down a bit; it looks like she's floating about two inches above his hand...
