You some effort there,
You did well with eyes shape, the nose shape is not done, but you were doing well.
for noses, remember the bridge is less wide then the tip and nostrils,
You need to paint from the eyebrows to the nostrils until you see it is correct,
the image show an example of nose.
About mapping and proportions, You did not so well,
to fix this try to increase eyes size in height and width, mostly width,
to fit the sphere, Look on the image.
the nose is too long and not so big, make it proportional to the face in a sphere( do not forget you are texturing to sphere).
Do the mouth a bit wider and try some expressions using the mouth, eyes and eyebrows, nose cna move, but not too much.
the side of the head must be well in sphere on front look and side look,
Your ears are too much appart from the eyes, remember the proportions and apply to the side too, the sides are difficult to get exactly like a normal head, but try your best.
nice to see your effort and interest.
