Work again, glad I get paid to draw so many girls :P
These (along with male counterparts and other ladies I can't show yet) are mages based on astrological signs. The briefs of these were very specific as to what types of plants, animals, dress and weapons were shown. Apparently everything ties into the sign's meaning.
Anyhow here we have Capricorn, shapeshifting mistress to 40 mountain goats and Aquila, ancient concept of Scorpio and sentry/soldier/huntress.
