Probably a good idea to elongate the face in the vertical axis, including lowering the jaw some. Right now the eyes & mouth form a near-perfect equilateral triangle, which is a common beauty-norm for a female face. Either bring the eyes slightly closer together or (my recommendation) lower the entire bottom half of the face a little, probably a cm or less. Bring the end of the nose down with this change, but perhaps not so much, just a slightly longer and thicker bridge.
Squaring up the entire jaw and skull would also be useful, with flatter temples and a more angular maxilla. Thickening the brow ridges is another option. I would also give the ears more flare, have them stand out from the skull more.
BTW, having spent over a year with female faces & form on my muscle system/universal figures, I totally sympathize with the mind-shift necessary to model a male face, which I’ve now started on myself.
