The Warhammer 40K version of the Ork is just about identical to the look the later Warhammer Orks had ( or at least the ones I liked!! ). They were bigger and brawnier. The sourcebooks seem to lean towards that view in all the pictures, so I went with that. It was also easier to find pictures of 40K Ork heads that were not helmetted .... I wanted a bare-headed start point! The source material also pretty clear on the muscular nature of Orcs...so I have gone for BIG arms! Not sure about the hair/crest being proper for Warhammer, but I loved that look in 40K

Big muscles ... small brains....that's Orks!
