Oh by the way, I found this chart a while back to help me with my drawing:
Emotions and Facial Expression
Now scroll on over to the one labeled "Seductive." It's in the yellow tree (the one that stems from "Smile," i.e., happiness/good feelings).
It says this on what a "seductive" expression should look like:
This varies with the personality, but this is an example combining some constants.
- Head tilted forward as if bowing, a submissive cue showing approachability.
- Bedroom eyes
- Sexual attraction dilates the pupils and tints the cheeks red
- Lips everted in a pout to signal harmlessness and availability (both sexes)
Renaissance women used belladonna extract to dilate their pupils. Men unconsciously picked up on the message and found them more attractive. As for the rosy cheeks, they are simulated by applying blush.
More tips about courting/seductive behavior:
- Courting couple slook down a lot when speaking.
- Both men and women tilt their heads as a flirting cue.
Now let's see...
- Head tilted forward: check.
- bedroom (heavy lidded) eyes: check.
- lips pouting: check.
She's not blushing and her pupils don't look dilated, but there's a lot of light which would cause them to constrict anyway.
Someone's comment on bedroom eyes reminded me of this.
