For all the convenience they bring, maintaining multiple robotic limbs can be a frustrating task. Cybernetics and robotic limbs are still fairly new to the consumer market, meaning most designs still have a few real-world kinks to work out. The elbows on the IDX-9600, Ms Mahigan's favorite set, are notorious for collecting dirt and dust, and require regular maintenance to keep them from freezing up.
This will almost certainly get colored in the future, but for now Halcy0n is still taking really cheap commissions, and will draw pretty much anything you can put in front of them. I will always treasure being told that the head moof was "probably one of the more normal characters I've been drawing lately."
