Ah, I get what you mean.
Yea, she's kind of squatting, as if trying to hide the boner or in the middle of standing up. You want a pic of her standing up straight like most other characters, gotcha. Well, so far there's only one pic, so who knows what's in store in the future! :D
About clothes... I dunno, I kinda like the "rags".
Note she really doesn't show much less skin than Hiro (who actually has his legs and arms covered -always speaking of the default look-). Maybe she's not interested in being dolled up, or doesn't knows how to. Trudy is sort of a tease, and clearly has more experience. Besides, Kylira's look match her personality: awkward, not sure, and accustomed to be alone. Kind of a wood's hermit.
Maybe a dolled-up version could be shown for the brothel (if/when you tell her to go there), that would make sense, as the Madam would want her "girls" to be "prettier".
Or have some talk options where you can give her tips to dress "better"... she could ask, or having Trudy too in the party unlocks the option -she might criticize her looks and give her tips-, sort of how she scoffs at Urka.
In any case, this is maybe an aspect Majalis (they!) isn't interested in developing (since it doesn't really adds much in terms of game content), but remains to be seen how much RPGing aspects they're going to add.
You need to look at the big picture:
This is a game about androgyny, not straight up feminization. I don't think there's a real need to have everyone look like pretty k-pop girls.
-We have Hiro, which it's an adventurer, and looks somewhat "normal", more generic (what can be "normal" in game terms... not slutty or overtly super girly or produced. That can be achieved in-game). Physically it also looks more standard in proportions.
-We have Trudy, which it's quite the tease, sort of the "tsundere" type of character, flashy and produced. Physically she looks more voluptuos, it fits her role of being a show off (the type of cocky *pun intended* veteran adventurer)
-And Kylira, which is kind of the "adorable in their weirdness" character. Physically she seems slightly taller, even a bit lankier compared to Hiro and Trudy.
So, the big picture is quite varied and original.
I do agree the Turtle could have more interaction.
Facepalming at certain battle outgoing would be hilarious.
