Well, Colin...
If she were looking to her left (say - like in your examples) - it would be easier for me to agree with all that. And even then - I had
a thread here some time ago, where I tried to figure out just how much space should be there for my model to "look into", and I came to conclusion that "how much" is actually a matter of taste.
In the case at hand, on the other hand, she looks straight at us. Let's compare this to the classic:
Mr. Vermeer put his model's eye, which is closer to us, smack in the middle (on horizontal axis). In mine - maybe it's a tiny bit more to the right than in the middle. That tiny bit is worth fixing, I agree. The rest is a matter of taste. Do you agree?
