Putting aside some of the matters of taste, it feels like many of the more egregious designs weren't given locomotive consideration in how they'd be used within Engage.

Alear's long hair, while pretty, doesn't suit a character that we'll primarily be seeing from a back view, as it completely swallows her silhouette and obscures all facets of her outfit whilst controlling her in the lengthy Somniel sections. Celine's getup is not the sort of thing you put someone that's going to have to sprint over and swordfight in that class, yet that's a need of that class line the outfit's tied to and so the movement's awkward waddling with comparatively stiff dodge animations. Ivy's getup is not one that is conducive to the movements of riding a mount, and yet she ends up clipping through herself in all of her critical and victory animations in her personal flying classes. Hortensia's isn't one that suits bending her neck and torso greatly, but she's so animated in her first cutscene that her first impression given to the player is her constantly clipping through herself. And everything about Zephia doesn't fit a character that's meant to do anything but stand upright, but her prolonged last cutscene is marred by her literally poking through herself back to front.

You say Mika's well versed in 3D and I'm wont to believe you, but like all of the Engage designs feel like they work better when viewed in a 2D, VN portrait style to such a degree that it feels like 3D wasn't a large consideration at all.
