I'm having some creative problems with this character, so this is almost a reboot. Until I took a second look at this image, I seriously thought of counting the character as a failed concept.
I'd written at least one short story featuring Tanagra. But trying to match artwork to that storyline has proven problematic. However, I like the character more than my original character concept.
Since I was designing a superheroine, why not keep the character but change the nature of her powers? And then write a different origin story?
