i feel like im completely fucking blind. I understand the loomis head in theory, but when it comes to actually looking at a picture and drawing an accurate one im struggling. I think my biggest issue is figuring out where the sides of the sphere are cut off, and how that actually relates to the face. Is the edge of the eye the end of the front plane of the face?
second thing is im having a very hard time telling the orientation of heads when theyre at slight angles. I cant tell if this head is looking up or down. The fact i can see so much of the bottom plane of this girls nose makes me think shes looking up, but if i look at the brown line it wraps around the head in a way that would imply shes looking down.
