Re: A more feminine martial art
There is a Chinese style called Pi Qua Zhang that might fit your needs. It's a very soft, open, flowing style. It is actually considered to be the feminine counterpart to another style called Baji Chuan, which is very hard, closed-off and thunderous.
Though it is difficult to find good info. about these styles, they're on the web.
Actually, that's something that could work out well as a theme for both of the characters you mentioned. There is also a linking form that puts these two arts together, combining them harmoniously.
IRL I study these styles, so PM me if you have any questions about where to look for info.
