Well on the one hand they're three beautiful, immortal and infinitely thirsty women ... on the other hand they're quite literally Out for Blood; all told, I think poor Mister Harker had the right idea when he made his escape from Castle Dracula and didn't stop running until he reached Budapest!On a less earnest note, please allow me to compliment you on balancing the need to keep these "Weird Sisters" a unit with the desire to give each some share of individuality; I especially admire your retention of their canonical hair colours, while including a subtle distinction to help audiences distinguish between the two dark-haired "Sisters".Whenever I imagine the "Weird Sisters", I tend to think of them wearing clothing they've acquired through brutally straightforward means - in the same way that Count Dracula appropriates Mr Harker's wardrobe, although usually without any victims surviving - with the apparent hierarchy between the "Brides" (the Blonde would appear to be "Big Sister") being represented by the quality of their costumes (the "Big Bad Blonde" wearing the newest & the most fashionable pieces, the middle sister wearing the less fashionable new pieces or the more intact pieces of older clothing, the third wearing whatever happens to be left - possibly because she's a little more feral than the others).I have to admit this idea might involve a little TOO much fussy detail, which may distract readers from the flow of the story.
