Hi
I would suggest following :
when painting eyes, start with the basic shapes. remember an eyeball is a (nearly) spherically shaped object. don’t forget to shape out the eyelids (upper and lower)
there is a great tutorial on painting eyes on Linda Bergkvist’s website.
also, when drawing a horizontal line between both eyes, that line should have a 90° angle with the vertical axis of the face. Her right eye is positioned too high.
The mouth area usually extends in width to these 2 points where if you would draw a vertical line upward, you would reach the center of the eyes.
I’m also missing the cheekbones. Checking some photo’s of human skulls at different angles will surely help you with this
Looking good so far Sheri! really looking forward to see your progress
