Oni-Link insanity was done using a mixture of brushes and filters. It's kind of my "signature style." I've seen people similar to my own style, but no one really close.
Anyway, I also used some Lighting Effects in Photoshop CS3 to really darken Oni Link to give it a more sinister feel.
I feel the same way! So many things I've seen, even in the last few days, I've been blown away by and I just have to ask "how did you make that". haha
