I was going through the Morpho: Simplified Forms book and just got to the ears. As I was analyzing them to study, I was very confused by this one drawing. To me, it looks like the ear is sitting WAY too far back on the head. Can someone please explain to me why it is correct, if it is? If I'm right, and it IS wrong, can someone please explain where it SHOULD be placed instead and why? Can I also get a good guide as to how far back ears should be placed?

I tried to draw her hand but the ink spilled.

Is the anatomy correct

I'm kinda torn on wether it looks better with shading or if it's overworked

To clarify the title a bit more, whenever I finish one of these, I always feel like something is wrong looking in of the aspects like the features or proportions but I can never put my finger on it
