The original image and my new version side by side with the focus on the girl since she's the centerpiece after all.
Noticeable improvements to my digital drawing is that I have a much better sense of how to use tone and color now, especially with regards to shading things like skin. And I'm more consciously aware of how much of a difference curved shapes compared to sharp ones make on defining the look of an object, character or anything really. Mechanical stuff tends to look best with sharp hard edges while the softer you want something to look the more rounded you'll wanna make it. I contemplated making the "human" parts of her body more natural looking or realistically shaped and proportioned but I feel the exaggerated cartoon-like sexuality of her form is important to the idea of the image itself. Were she a realistic human based android she'd have a much smaller head and wider waist for example but the "sex object that doesn't want to be a sex object anymore" concept wouldn't quite work as well I don't think.
I like to think of it as the ultimate version of an anime waifu girl who decides one day she's fed up with her creepy sad pathetic "owner" and deals with them in the only way a machine knows how; by ending their life so they are no longer a factor.
The reason I loved drawing this image again was mainly because of the nice contrast between the somewhat sexual soft girly bits compared to the almost horrifying mechanics that represent the character more truthfully as I've long been a fan of the "attractive thing that is very alluring but will destroy you if you become entranced by it" idea, which obviously dates back to ancient times.
