I have made eye contact twice and captured at least a dozen on video and they look remarkably "human". Mary Green took heavy criticism in the 80's and 90's because she was describing them with human features. The "old guard" had trouble accepting they did no look like a large ape.
The major feature that is different from most humans and appears to be very common with the Bigfoot in my area is what we call the "Goggle Look". They have a pronounced brow and deep set eyes. This makes them look like they are wearing a pair of dark goggles. This feature is interesting and makes it difficult to see their eyes unless you are extremely close.
This Charles Middleton drawing comes very close to representing the general look of the Bigfoot in my area of the country.
Below is a drawing I made based on both my eye witness encounter and video captures. I believe this to be a young female that I call "Scout". She showed herself to me briefly and we made eye contact back in 2010.
