I focused on the face of the model today and I discovered that I need to work on drawing faces.
I don’t think I have an issue with drawing faces when the pose is 20 minutes long but when the pose is 5 minutes or 10 minutes I rush the face and it looks bad. There is also issues with the face not looking like it is part of the head like the silhouette is separate from the facial features. That is an issue of structure. Maybe for the next few days I just focus on the portrait of the model down to the shoulders and nothing else.
