Representation of Night Gaunts

To really get a feel for how I want the night gaunts to look, I've searched the internet for the representations of these creatures through the eyes of other artists.

A monochrome piece, the night gaunt seems to be very simple and just a silhouette - ideas for how to represent them as black without making their skin actually black?

Melissa Chiu

Muted colours though all related to the colour of wounded flesh (looking sore or bloody). The wings actually don't have a function and the horns are mis-matched.

Marc Tremblay

Despite being described as slender in the poem, this version seems quite well built - however in relation to body fat, there is none, muscles and other anatomy is clearly on display.
