the light from the window

Sigfrid,

I really like this photograph, overall tonality and desaturated colors are of the first class. I like the combination of subtle, vintage-like light and geometry of composition I often see in your works. However, I think that this one suffers from some problem with perspective/geometry. The converging lines of dark tiles give the impression that the floor edge is not parallel to the lower edge of the photograph. I am not sure if this is what you want as the photograph is all about geometry. I think that if you crop it to remove the most left line of tiles or even two of them you will avoid this effect.
