I see elements from all four fourth generation gundams. The cannon has a Seravee element, with that gem in the front, the legs have fins which make me think of Arios (transformable maybe?), the shoulder mounted GN Drive reminds me of 00 -obviously- and the various plates has a Cheridum element, especially the face for some reason... to me anyways.... The claws are a nice touch -GN-X reference?- and the feet make me think of Japanese sandals or at least a version of them, female I think... so to me it's a nod towards Susanowo, who also makes me think of Japanese wooden sandals. This in all, is a very dangerous mech, since it combines the strengths and features of the four gundams and several others. Very creative.
very nice job! i can't find any resemblance with 00 in this one, if you aiming for sniper or cannon unit, I think it's better to call them Cherudim or Seravee. It's up to you though, you're the creator
