Steampunk/Elizabethan-verse gentlewoman?

Incomplete sketch of a character I envisaged today while walking the dog, a gentlewoman riding an andalusian through a steampunkish metropolis, which of course I haven't drawn.

Very little reference for the horse - I had a pose in mind and references weren't working for me, so pretty much all I got out of it was the right shoulder. Otherwise all from me brain.

inspired the hat with her latest drawing xD Mine isn't quite as awesome
