Feel as though a lot of the texture is lost in the skin because of the excessive smudging, makes the skin look really blurry in parts such as the right side of the face. Skin should have the same sharpness that the hair has, looks odd how in focus the beard is compared to the cheeks. you should try to get the values by using a simple shading method, will make the image alot sharper without the use of blending/ smudging.
