There is a saying that the eye is the window to one’s soul. It is so true in portrait photography. When you look at a photo, if everything is perfect but the eyes are blurred or don’t seem right, you may reject it eventually.
These are some of my photos with only the eyes as a main focus. Even the face is absent, you may still feel a connection with the person behind through his/her eyes.
Of course, all credits belong to the artists/photographer who had drawn/captured them successfully.
