Eye

They say that the eyes are the window of the soul, simply because when we feel the first thing to reflect it, it is our gaze.
The following drawing is part of my collection from last year, I did it in the academy where I study. It took me about a week to finish it. The materials I used were:
Pen 3B and 5B, cotton and a brush that also helped me to blur.
Any suggestions you can leave it in the comments.
