Aside from all the know-it-all comments that say it's just a guy in a suit, (I just cannot see how it is so "obvious" to so many, it's not to me) but still some things just don't look right.

Like the eye-like reflection facing towards the camera as the body indicates he is heading away, and so that is a rather extreme amount for the head to be turning. Which it just doesn't look like it is doing.

They just don't fit right or look right, one white reflection and one red?

I think it very well could be a real bigfoot, but because of the strange oddities occurring and/or doctoring done to the photo,

It's unfortunate that this is strangely uncompelling.
