Oh wow, I would love to have my two fantrolls done! : DD
Here is my first girl, Rolyat Neirbo, the Alternian purple blooded seadweller.
(this tektek should probably help you understand what exactly she's wearing because the sprite form doesn't make it easy to tell)
She looks pretty badass, but she's not punk-ish at all. She's not even a FLARPer. Her horns are based on octopus tentacles, and as you may have guessed, she's got an octopus for a lusus. Her sign is based off a book symbol, but it doesn't mean much other than as a connection to why she loves books so much. Her belt buckle has her sign on it, as well as different sized circles along it to represent bubbles. As for her expression, she's pretty calm and collected, so maybe a tolerantly amused smile? I'd suggest looking at Rose's talksprites for reference, possibly. Action, maybe her arms could be crossed?
Next is my last fantroll, Canisa Renees, the Beforan yellow blood!
She's really timid/worried/shy about every little thing, and she is very gentle. She has no psionics, which isn't too common but not rare for one of her caste. She is very heavily dog-themed, in the way that her horns are supposed to resemble floppy dog ears, the pawprint on the waistband of her dress, and how her sign is
Canis Minor. Her sign is not on her dress, instead she wears it as a necklace that doubles as a key for a personal treasure box of hers. For her expression, maybe she could be biting her lip nervously, or frowning in concern/worry/fear? Her eyes are usually pretty teary, so she could also look like she's about to cry. As for her action, maybe rubbing one of her arms or twiddling her fingers(or no action is fine!).
One last note that's not very important, but you still might want to know, is that they're both adults around 9 sweeps, like the Beforan ghosties. Their eyes would be filled it with their respective blood colors already! And as for breasts, Rolyat has a pretty nice rack, while Canisa's rumblespheres are nothing really impressive(but not non-existant!).
