Bloody marvelous.
I utterly adore how warm and sensual this picture is. Warm on multiple levels- at that. The palette and background do imbue this with a sort of 50's vintage sex appeal that I find to be a rarity these days.
Also, might I challenge you with something? These characters appear to be original- but I wonder how you would fare with someone elses work. I wonder how you'd pit yourself against tossing up Gadget from "Chip 'n dale: Rescue rangers" in a more mature theme. I see you've done this with XJ-9, but I don't really think that this really touches upon your talent as the protagonist from "My life as a teenage robot" is simply.... Well... Clear-cut and mechanical, if you will. Her outlines and color scheme almost seem slightly monochromatic and this really does inflict a sort of 'static' (if you'd permit the term) simplicity that I'm sure differs greatly from something organic (and in line with half of your creations- hailing from the animal kingdom).
Please keep making more. This is really impressive.
