Wow, this is awesome! And so easy, too!
followed the tutorial straight up, but stole the idea to use a relief from an early post.
I love the Relief effect on these, it really makes them pop out!
Simply used the Edge Detect and relief on this one, I think it looks amazing. (Coloured it to red with the curves first).
On this on I set a negative twist on the duplicate layer, and used the relief effect again.
