I kept the painting straightforward with a basic green with purple accents on the fins. I've always liked Khurasan's sculpts and these are good examples. Nice clean details that are easy and quick to paint and poses that are animated and full of life.
Ah, it's great to see some Cthulhu stuff roll out for the Challenge. Wonderful work Brian. I didn't know that Khurasan did these in 15mm - very, very cool. I particularly like the figure who is positioned forward on his (her?) right fist and I also think your choice of using purple tones on their dorsal ridge is a good one - it provides a great contrast to their green scaly bits. I look forward to seeing the other seven!
