The mouth looks okay to me. I've seen plenty of people with that "dimple" in the corners of their mouth. The eyebrows: You may have to set all expression dials to 0, then export this particular morphed face as an .obj file. Then you can send it to an outside modeling program and fix the eyebrow wierdness there before importing it into Poser again as a character face morph. The widow's peak... I donno. The image isn't close enough to see if it is a texture problem, or a problem with the hair piece itself.
