Ranting aside, I just decided to draw Kevin (changeling from ‘Slice of Life’), Pharynx and Thorax as dark fey (though they were mostly based on dark elves). I gave them distinct marking to not only to display their roles but to show that Kevin is the odd one out.
Thorax is a regular worker, not meant for much more than maintaining the hive, hence his lanky and short build. His markings are to show others his role in the hive.
Pharynx is a soldier. As such, he doesn’t have as many markings as they’d draw attention to him when defending the hive. He was hard to color since his color scheme is a lot more… colorful than was necessary.
Kevin is a medic (if it wasn’t obvious). Kevin belongs to a different hive than Thorax and Pharynx, which is why his marks are different from theirs.
