Theyebrows are modeled as if it was already rigged in fact. Well, that's some angry facial attitude which brings the eyebrows down over the eyes.

It's close to the pic from Kong clearly , but it's also true you'd better model with some neutral attitude first. So, relaxing the major angle edge them a bit upwards.
Then , sculpt a copy to set attitude.

Hope that helps in comprehension

With the nose, i just don't see, i like it so far (except missing bridge).


Nice MacF, keep it up.
