Triad coloring

I've been trying to brush up on my coloring skills, so to speak.
has been helping me quite much, teaching me about different methods of coloring (...and stuff), over at playing.se. (thanks!)
Anyway, he told me to do a picture using triad coloring, and I tried it out with this picture.
The site [link] really helped, too.

Made in painter, didn’t take that long.
