I recently commissioned my good friend Kabuki Katze to do a picture of ROJ character Green Wyvern in what I described to her as a "Frazetta type" pose. She just finished it, and her blog entry about it is worth reading.
"Smokin' Sentai Stunner" @ Kabuki Studios
I'd also suggest you check out her posting of the picture on deviantArt to see what all the cool kids are saying about it.
Thanks for such an excellent piece of artwork, Kabuki!
