Your eyes, which are perfectly normal, tend to choose the "version" of the lady that gives the most complete information about her eyes; where are they directed, what does she look at. In spite of the softness, the reflection reveals this better than the silhouette.
It seems to me that the effects of the reflection is even more pronounced, though the focus is on the sitting half-turned lady. My eyes seem to stay with the reflection. Do I have odd eyes?
Best wishes, Lilia
