Heh, this was my very first Ork about two years ago.
I struggled with painting him so much back then. I'm happy to say my painting has improved a great deal since, but I don't really like doing it nearly as much as converting.
This guy was my 2nd ork, first conversion.
I did all these with four colors, mind, and this was before I learned what sheet styrene was. Those days are comfortably past me now.
