This was done in Photoshop. I used the soft round brush with a combination of blend, burn and dodge. The spatter brush was used for final skin details. I had fun painting the beads of her necklace.
@noonespecificThanks, I find the eyes are important features that bring life to the drawing. I took some liberties and strayed from the photo reference a little.
You've really got a knack for eyes and and small, very fine details.
youve got some patience going through all them beads ;)
