Original acrylic painting by WordSword. Work in progress. Find the hidden face.

This painting is not finished yet but it's not far off.

There is a face hidden in it. I didn't notice it, it was my spouse. He explained to me where to see it.
It's very vague and not easy to find, but ones you see it, it can't be unseen.
I'm not gonna say where it is thought ;P
Maybe when it's finished or someone else may notice it and put it in the comment section.
