I also think the sculpt of the Ancient evil really lends itself to UV painting.
UV is a real challenge. It took quite a while to get this figured out, but I am happy with the way it turned out.
I wish the Slither would looks as good in the photograph as it did in person. It just looks mostly green but there was also a TON of saturn yellow highlights on all the scales and teeth.
It definitely paid off the efforts, mate, it looks fantastic!
