Offline life drawing classes

This semester, life drawing classes changed to offline, and our teacher allowed us to reflect the feeling of live sketch. I was able to complete the corresponding sketch within the specified time, but the teacher found a problem that my lines were not smooth. The teacher checked my drawing style, and she corrected my painting style. In the process of arranging lines, the lines are more rhythmic and smooth, but the overall effect is not very good. I believe that with the practice of the new method, my level will change qualitatively soon.
