The cowl looks fine if you are going for the Batgirl look. Batwoman has an open cranial area for the hair to poke through. The Bat ears are part of the domino-style mask. A solution to the classic look would be to mold the hair to the mask as one piece, perhaps including morphs for the hair in different motion styles. That alternative will definitely be a challenge. Might be a little out of your realm of expertise. But again, this is your interpretation and that's what matters. Great job, so far.
