This is an updated character concept of Model ZXA that I did last year.

There are armor differences on each character. On Vent, his shoulder armor is much broader making him look more masculine. He also doesn't have extra armor parts on his belt unlike Aile. On Aile, her shoulder is less broader and I added extra armor on her belt to make her hips or thigh look bigger and feminine. There's also subtle differences on each helmet that's meant for each character.

Both characters features the ZXA Bullets. I might do one where Vent has the ZXA Saber and Aile has the ZXA Buster if I just don't get lazy though. XD

Here are the separated pictures of the main artwork.
