You are on a good way.
My crit -> Overwork the upper skull.
Everything over the eyes is to short.
Not the forehead only.
Could be one third taller.
Good luck!!
Thank you all!!

Looks great, really a lovely portrait. 
Cheers, David
Talk about big. Anyway, thanks for the reply. I guess my image have too much color, hence the issue with uploading big image size.
About the image, I think the tearlines under the eye can be more smooth. A lot of areas, like the collar bone have a slight wavy surfaces. I think this could be due to too much sculpting work in the high polygon division region.
Normally, I recommended people to do sculpting at the min level possible to get the correct shape, & use higher division level for finer details. This way, you can maintain a smooth shape, while having fine details when you need it.
are you doing any blue red green orange under painting to the skin? blue for veins blood … that kind of thing?
chalkman - thanks, david!!
pkd - thanks for your words, i tried to adjust the areas that you said, thanks a lot!
BlackMath - no, the blue veins and this stuff i do for the epidermal, the under skin as you said, the subdermal, i did more blurried, redish color.
some update with light tests and another angle, c&c are very welcome!

the skin may look a little too blotchey/dirty to me but that might be part of the plan for the final image.
