I think it is awesome that in your drawing you 'display' the damaged boob more, while covering the other with armour to protect the heart. It definitely brings attention to the boob and gives her a more feminine look, however to match that the damage done equals it out with a ' yea that's right, I'm a female and i'll kick you'r butt any day.' kind off look.
I agree that she should be proud of her girls, but not obsessed and attempting to show them off at any given chance. After all looks most likely won't save you'r life but the practicality of an outfit might. that's why I like what you have done in you'r drawing as it get's both messages across clearly; there is a certain female attractiveness but that is matched by her battle hardened character that clearly shows in the scars and overall look.
The armour looks awesome. It has a slight streamline look to it without it going overboard in the feminine area. It swirls and curves smoothly, but also displays sharp looking and blunt looking points and edges.
You'r armour is a beautiful example and mix of a kick-ass female that can equally match any male in combat without loosing her feminine touch.
This is however only my opinion as another female hunter.
I look forward to seeing the end result
, and hope that I have been of some help.
Happy hunting and good luck
