Faye is always a work in progress. I'm never satisfied until something is perfect. I feel like I'm getting closer to a style and design I can finally say I like. Not only for her, but all of my art. Even still, I'm never going to stop experimenting and working towards improvement.
She certainly has come a long way though.
For a character who is post TF TG, she is still always changing and evolving in her "base" form. Cough...hint hint.
