Geest comparison - original vs copy

This is a side by side comparison and you can see that there is things quite off. DOH! Ok, not to be discouraged. The purpose of copying is to learn and in learning mistakes are made. The reference I have was a printed copy of the painting and here are some of things to fix. 

• overall color of the skin is much too yellow.
• lips are too red and saturated. (the hard copy ref was that color I swear! lol)
• Some shadow areas need to be punched up.
• frills or ruffles value need to be toned down and detail added.
• Hignlight on the nose needs to be toned down.
• transition tone between the left eyebrow and forehead.
• Hair details needs some tweaks.
• cast shadow under the nose.
• ears needs more modeling.
