Two not too recent drawings.
Nellie is a malfunctioning pleasure droid. Originaly, she was brought to a foreign planet as a companion of professor Coalsky, researcher of strange alien fauna. Due to a high levels of the humidity on the planet, she flipped out, and instead of providing some pleasure for the professor, she started dancing to a weird tune comming out of her head.
Local alien species found it hugely entertaining, and she got quite a following amongst the little critters.
I have a few more sketches which I never got to clean up, but I will one day soon, and the story will be explained better then :)
