Hi Hassan, this is a beautiful piece. The lady in your drawing seems to be smiling, which is not so in the reference image, and this smile makes your drawing look ethereal. It's beautiful!!
Heyy man! your art is really awesome.. I've been watching your videos lately while i learn more about portraits and it really helps me understand things so clearly than any other methods I've came across.. you're a great teacher ❤ thanks for existing ^_^
