The Gladewyrm. This is the last of the Sylvaneth endless spells. I like him. I have a surprising number of worm-like monsters now (Carrion Crawler, Purple Worm, Remorhaz). Now, I just need that huge one from Reaper's Bones line to rule over them all!
I tried something different with his runic head thing. Basically, it consisted of painting white into the crevasses and then wiping the excess away. Then I followed up with a glaze of the color I wanted the runes to be. It worked okay, I got talked into choosing red for the color and it had the same tonal "level" as the surrounding carapace and didn't pop like I wanted it too. I tried to fix it by then glazing yellow on it to mixed success. It would have looked better if I went straight yellow or left it white. I think I need to work on that some more.
