I use artwork for inspiration and female characterisation is a distraction (for obvious reasons) rather than an inspiration. Yet many authors have written tales of beautiful women being rescued by some hero so clearly gorgeous, voluptuous women is a key to many tales, otherwise they might not be rescued. (Shrek being a notable exception :) ).
Today's fantasy seems to turn that on its head and an author needs to have as many female leads as male. Certainly many of the fantasy artwork depict Amazons with spears and swords who seem vary capable warriors.
Myself, I still like artwork that inspires and the Tolkien artwork below does just that (and not a naked woman in sight).
