Nice site and some great pieces of work. On the subject of copy protection, I can't help thinking you've lost your way a bit on this NT. The pieces are very individual so they are instantly recognisable. If someone has so little resources of their own that they have to resort to stealing pictures, it stretches belief that they would steal yours. What are they going to do if asked to make another, when they would be unlikely to have a clue as to how to go about it? They would struggle to sell something they had little knowledge of in the first place. The way your pics are plastered with logos looks a bit, well, paranoid. On balance, I think most customers would appreciate a decent, uninterrupted view and if that risks a 1/1000,000 chance of some t**t copying your pictures, so what? Best of luck with it anyway.
