Here is a picture of my fan-character, Sofonisba. She's named after a female renaissance painter, and unlike the other turtles, she is not a ninja, but rather a gaucho-type raised in Brazil. Her weapons are the machete and bolas, and when she first meets the turtles, she speaks only Portuguese and Spanish, but will likely learn English in order to communicate with them.
Her attire is different since she grew up roping cattle, and is not accustomed to hiding from people since the neighbours in her village all knew her and treated her as an equal.
I'm attempting an action pose but I'm not that good at them, nor am I great at perspective. I do like how the background turned out though. I gave her a different type of costume so people wouldn't confuse her with Venus from the live action series, and her mask is mainly for design purposes. She might be into Zorro and Anime as well, but either way, I don't think she'd be complete without the mask.
