Excellent post dear friend @opheliafu, in images of faces you can appreciate the profecionalismo of the artist, I am not an expert of the subject, but I have observed that always the artists have difficulty to grasp the essence of the face.
However here you can appreciate the realistic features and looks of the work.
Congratulations on the level of profecionalismo that you possess.
Have a great start to the weekend
Thank you for these kind words @jlufer. This drawing is preparation for another piece I'm working on, so hopefully you will be able to see in a few days the next stage of my creative process.
