I never imagined the Slakemoth like this, i always thought it would be much more Insect-Like, akin to a giant moth. but i think your version fits as well. good job.
I'm loving that stringy form and position, as well as the sexy colours that mould together so well in his wings, tail, and tongue. And the sharp points. Can't forget them sharps. What a beautiful fucking soul-sucker. Gotta read his book now.
