I really like details on her armour.
If you don't mind i'll tell some of my suggestions.
If you draw female character try to make her hips more wider, and shoulders more narrow. In base model it looks like females shoulders lie one one line with her hips. And the whole torso is smaller then mens torso.
It'll be good to to study some fundamental anatomy if you interesting ))
And it looks, that you make strong lines when you make sketch. And then you erase them and draw on top. It's normal to anyone.
But to make your drawings better try to make your lines more soft and bright. By this way you'll have no need to push pencil so hard on final stages.
Sorry for annoying. =^^=
Удачи!
