Dumbledore's is more or less bang on, kinda looks like a Harris/Gambon blend... but, there's just a little something wrong with the Snape one. Like his jaw/chin... just... something not quite right. But then I couldn't get that part quite right either on a carved relief in clay a while back, cause Alan's face is just exquisitely detailed like that, hard to get the right depth/shaded details... Very nice otherwise though! Wish I could get the Snape one! <3
