Holy cow, I like this design so much!!! One thing is unclear for me is that shield(?). She holding that thing as a gun, but for shield is more usual to keep it with a whole forearm. But maybe is a superstition) . Or it's a giant mech-axe... Just curious.
As I understand, you will make her look Ukrainian by the flag colours?
One more thing, at her leg, does she have a wheels? That would be cool) Or it's a "shoes"?
