Agreed have planned to redo them to add the sleeve puffs , less wrinkles and tighter (save a few polygons too) , and shortern the skirts.

Better, I'd say shorten them so at least half the butt cheeks can be seen, and also the panties if the camera looks straight at them. Especially if the skirt for now can only be keep largly straight, unless you can somehow add physics to allow it to sway a little when they get beat around, such as ride up to the waist if upside down or knocked on her side. But man Agent AIka was truely something awesome. You cold tell the creators knew they were making something fanservicy. With the creative often low camera angles and exagerated defeat poses. I think this show would have been so much better if the Delmos wore outfits that showed off tones of cleavage, the belly, and th panties were completly thongs. If they were going to wear panties the least that could be doen was to draw it so the crotch showed the shape of the Delmo's crotch. One weakness of the live action short film and the female combatants inspired film, was that the girls either wore boring panties, for the live action Aika, or wore leggings and panties that barly showed off the butt cheeks.
I really love KO Corral's concept look of "Neo Delmos". Holy crap is this sexy, just needed a little more cleavage and it's perfect without simply being just a bikini.
