Dude - check the Painting chaos in 8 weeks thread in my sig
First few posts are some WIP pics of my Kholek conversion.
Just for the record, I used a carnosaur for the lower body, you can buy them seperately from GW mail order as well.
Also on the bitz list for me was the two weapons from an Ogre Tyrant, cut up and stuck together to make the hammer. Other than that I've just got a load of sculpting to do still - I really should get my camera out and get that thread updated with some of my more recent progress!
