Thank you all guys for the knid comments and compliments.
Progress is kind of slow.
Finished some details and started the coat. I also added some lights to the face as it looked a bit toned down.
For the coat i use a mix of skintone base, paynes grey, french blue, carbon black and a touch of purple madder. Highs with skintone base shadows with black.
Beside you can see three lights and two shadows applied.
