The Gladiatrix as I look at it a bit more, provides some ideas. My only nitpick is the shoulder pad because I'm not a fan of hovering shoulder pads with nothing to make it feel like it's connected to the outfit. The colors on the overall outfit is nice, but I'd probably change a few things imho. Other than that, it's nice.
The Siegfried kind of struck a bit as oddly bad. Bad as in I really like it bad. The more I look, the more it grows on me. That's just bad since I usually see something a bit more over the top from you. So Pocky Yoshi-I mean I may have to commend thee-I mean you for that.
The Tira is also nice and simple. I'd like a formula for the 2 different colored angel rings in her eyes. It gives me ideas for stuff on my own. If that's alright with you.
The Asty is my least favorite for how it looks, but you played with the rainbow pattern to make it match some stuff. So I guess it isn't too bad and it's one way to experiment. Like the Ivy one, just a bit more tweaks and I think it's grow on me.
Overall, Pocky Yoshi digged-I mean Pocky Yoshi speaking in third person-I mean, nice batch of CAS.
