No, I'm talking about TheHappySpaceman's two OCs, the guy who was talking about that topic.
Not sure what I'm doing that you're not, because that… doesn't hugely look like Noodle, lol. (EDIT: And that honestly doesn't look like Mina either, now I've looked her up.)
Actually, having thought about it, I guess complexity in the design is part of it. The two OCs shown take an elegance-in-simplicity approach to their design, so I guess there's more of a risk that they'll bear a resemblance to another character; if they have a relatively small number of defining features then it's statistically more likely that some other character out there will share some or most of those features.
Work in progress.
I think giving her a rad hairstyle would go a long way. Especially if it looked "robotic", like all geometric-like. I think since she's very inorganic-looking, having some more stylised and artificial-looking hair would suit her better than the semi-realistic hair she has.
Also the eyes. Having expressive eyes is key. Putting a shine on them would be the simplest way I can think of. If it were me drawing a robot in my style, I would make the eyes more oval-shaped (vertically) and give her visible whites and pupils, but that's just what I would do.
