That was the main thing that inspired me to draw this, actually! I just loved how delicate and feminine she looked in the picture, even with all that badass armor. I'm really tired of stories where girls have to give up their femininity to be considered badass... why can't we have both!
Yes, what gets to me is when the female character is only considered to be strong when they act like a man, and their strength proven when it's compared to men. I don't even mind if a female character becomes strong by doing the same things as a male character, as long as they're a female character who is being strong, not a female character who has become strong by acting like a man.
There are some execptions when the setting of the story means that the woman has to disguise herself as a man in order to have the chance to prove her strength, but even then it's a tricky balance between having a character who is a strong, man-like woman and a character who takes ownership of the skills she learns while in disguise.
And that's before you even get into the stories where being feminine can be a strength, or even just a normal part of a character - and not just in a "because it makes a strong character look weak and harmless to their enemies" kind of way.
