Ea’s definitely most proud of all of their eyes (save the left one on their face), being the only person in their family with blue eyes and naturally having the most aside from their mother certainly helps as well. They like to stand out, what can I say.

Is is reflected in the design? I mean, you can see the image. Honestly this isn’t even the best panel to show their eyes off, as they have 10 on both of the tentacles coming out of their waist.
Suen’s favorite feature of hers is probably her nose, although she doesn’t care much about her appearance aside from wishing her hair would grow longer. It’s just about the only feature she has in common with her father, and she doesn’t let him forget that fact.

I wouldn’t say it’s very reflected in her design, because that’s the kind of thing you can’t really draw attention to (well, more accurately, it’s ALWAYS the center of attention being the center of your face), but it does come up in the dialogue around when her father is introduced into the story.
