that detail.
i think...from what i can see, the eyes look a little bit far apart. also, the nose seems a little flat to me and has weird nostrils. they look sort of like they're in the middle of the nostril part rather than on the bottom. just look at your own nose for reference :) the bottom lip could be a bit bigger, too, maybe.
all this stuff could just be part of the android anatomy thing, though.
it looks REALLY good though, i love your use of color. and all of the little details are insane. you have a gift with painting.!
