Demons of Yeenoghu - Dretches & Quasits

I wanted to take a crack at redesigning classic D&D demons as if they were tied to a specific demon lord, with the idea that the power of these abyssal entities literally alters the lesser demons around them in their image.
Here we have a lowly Dretch (left) and Quasit (right) of Yeenoghu, the Demon Lord of gnolls, bloodlust, and reckless carnage!
