The movie Snape and Harry has never worked for me (Alan does have a sexy voice though and I'd like to think that Snape would sound like that or better!) I try to portray my image of them in my art as much as possible though sometime they are still off in a way I can't really describe. I think I can closest to getting Snape and Harry right in my mind is in this piece: http://umbrus.insanejournal.com/2109.html#cutid2 However, I like Ponderosa's, ac1d6urn's, Glockgal's, yukipon's and Lizardspots's Snape and Harry very much as well. They all seem right to me in some sense.
