I'm still fooling around with the idea of having some kind of a signature on a picture. I created a kind of stylized water lily (from this very image), then made it very small, with my initials on either side. If I put it on the picture and use one of the blending modes, I can make it barely visible on the picture. What do you think? It's still kind of crude if you look at it in large size, but small I don't think it looks too bad -- or does it?
