I can totally see it, but yeah a bigger picture would be nice.
Looks like a face to me, but unless it actually resembles your uncle, I'd say it's just a trick of light and shadow.
I see faces everywhere too.
You are aware that the human brain is prewired to recognize faces. You can find them in everything from pieces of toast, to tree bark, to rocks on
Mars. It is simple pattern recognition. It doesn't mean that the face is actually there, just that your mind is looking for patterns. º(*_')º
