Been forever since I’ve tried to draw, so these are by no means anything I’d consider “official”. Just some sketches as they come to me.
Here’s a Skyrender with a Dres on its back. I always pictured them as being more of a beetle than a wasp, with the Dunmer mounted on its thorax to free up its wings. This one seems to be missing its beetle shell, though...too hard to draw with everything else going on in the picture, heh. Bladed dangly legs (two much bigger/longer than the others, used as scythes) and a blur of wings as it skims over the salt plains.
