Razordon hunting Packs...how to?

to finish off my lizardmen army i got two razordons but I'm not sure how to paint them, and i want to do them really well because they're one of my favorite models....i know a lot of people don't like them but i do .

anyways, my paint scheme for the skinks is green with red scales and a yellow crest. if anyone has ideas on painting the razordons that would be great.

also i was thinking of painting them like the regular GW ones, does anyone know how they did that?

thanks guys

 

Christmas skinks?!? Is Sotek Claus around?

But on a more serious note, all I can say is "brown".

 

I did mine with a wash of bestial brown, and then a wash of fiery orange, ad it turned out pretty well, I think. They look lizard-y enough, but still have a look that makes them stand out from the crowd a bit.
