Quicky experiment that I think turned out rather well, and decided to share as my first post here! (Yey!)

I've been in search of the "ultimate" iridescence tutorial... and a lot of the ones I try out just plain don't seem to work for me. So, I took a little from here, a little from there, observed a lot of humming birds aaaaand, tada. Iridescent horse. Whacha think?
