So, you did it. I have been thinking about that reflection all the time
The double vision for me is caused by the main shadow of Ranarh going rather consistently to the upper left, while the fremai reflection goes every which way: top, right and left at the same time.
And while Ranarh has sharp edges, the fremai is rather blurry, strengthening the cross-eyed effect for me.
Bear in mind that I have really no experience in art. That is a layman's opinion
I still like that picture.
