The complexity through simplicity is always so awesome in your pieces. On Friday and I were discussing the slight color distortion you get on some of your edges and we were hypothesizing how you do it. Care to share? We came up with some techniques that come close to simulating it but couldn't quite nail it.
^_^ thankyou! Um, so when I've finished a piece I'll flatten it, and then I get the colour shift by using the smudge tool very slightly in just the red channel. (you can do it on the others as well of course but red looks best).
