Originally a submission to the contest, the idea was about a witch amidst the forest/hiding in a cave concocting a potion that would transform her into a strong devil/succubus creature that she so desires to be (meant to be card 4 and this is card 1). This being a full illustration in a long time, it's challenging since I'm so used to just sketching but not fully rendering out my sketches. Learnt a lot in regards to almost finishing this, putting it away till I want to get back to it.
Oh i do love the Lady's lurid look. Her expression very much says that she is a consummate professional who really, really loves her work. Something tells me that she rarely, if ever, gets a realize form the subject before she applies her mutation potion. No doubt being assured that whatever she turns you into will not be able to object.
Thanks for liking her facial expression! Her potion is mostly meant to turn her into a stronger form, and I was planning for in card 2/3 to have "failed experiments like snakes/creepy animals hanging around but never got around to doing it.
Oh but we all know that as a Sources does find herself growing stronger and stronger, she finds that she can never get enough. She might in fact even come to delight more in her failed experiments than the ones that go as she had planned under that intoxication of strength.
