For my part I'm very happy with Katla's new Un-taki hairstyle (or lack of it). I do miss the old crazypunk hair and Ni-Kunni faceveil tattoo Ruby used to have, though.
I can see why you like this picture. The expression is great and creates a lot of tension in the picture, making it appear dynamic. The background frames the character's face nicely, and the dark clothes combine with that to bring the face more into focus.
That effect is significantly diminished by the lighting, however. Half your character's face is covered in shadow, and I think that's doing it a disservice. You may have intended the lighting to evoke a...well, grimdark mood, but the background, clothes and wonderful expression all combine to do that already. The only thing the lighting (or lack of it) does is make the face more anonymous. Change that, and it will make an already good portrait better, imho.
