Drawing is really good. I can see a difference in full spectrum of line weights. Was your aim the depth of field for lines? In that case the girl sitting back to us is not in the focus. The camera focus is in the middle of the table. That makes eyes of 4 girls somewhat in the focus. I do not know actually if the DoF equals the focus of the camera in the art. But I saw some artists drawing very close trees and objects blurry so that we do not focus on them.
