that looks cool! do you think it was influenced by Amy's Another Eden? Amy herself looks heavily influenced by FF7's Tifa :-)
but you're right, her color scheme and especially her pose has a strong resemblance to Amy's 5 star art.
the character designer for Metallic Rouge, Toshihiro Kawamoto, also did character design for Cowboy Bebop. do you think he plays Another Eden? if so, that's a great homage and compliment!
if you see the trailer video on their website, i see some influences of Neon Genesis Evangelion too in her transformed form.
