Finally finished my grandmother's portrait

This portrait was extremely hard for me to get the right tone. She had such fair skin that the color started to look like the color white, right from the tube. However, about midway I started to make the skin tone darker with shades of brown in it, which brought her face out from the "blendings" of a wall.
*I will definitely have to work on the hair next time, make it more individual than collective.
