Hmm, I must try that! I used to use Alien Skin many years back. Have you ever compared it to Nik Silver Effex Pro? Anyway, I do like your result. The consistent "look" has allowed us to enter into an imaginary world of B&W that is, like a business organization, or an ancient religion, so internally consistent, that it is, once you enter within, for all intents and purposes, absolutely truthful and real! Your processing has pulled us in in this way and I really believe I have been, there too, listening to the choirs and concerned that my camera might disturb them!
Great job!
