Bandenk,
I think it;s a good start but I don't think it's done yet.
I like the background, it really pops now.
It really is lacking contrast on the chest compared to the face, I would try and burn in some more shadows and try to play with the apply image, vivid light at a low number (3-8% ish), that will likely plug the shadows in the face so doing it on a duplicate layer and erasing some of the effect layer may be needed.
The skin looks pretty de-saturated now, even if your going for that look I would add some more color in, as you look pretty gray in the after photo.
I might remove some/most of the blurring in the face, especially under the eye's and cheek bone.
Just some idea's, keep it up
