Hi Scott, I did some draw-overs, just the start of the process to adjust proportions and perspective first. The main thing I noticed was that her features needed to be shifted in perspective and to the right. Note the arrows.... the nose, dimple, mouth shifting right. On your version, the head itself is in 3/4 view, but facial features are beginning to slide around to the front view, which gives the impression of a less prominent nose. Some of the shifts involved turning circles more into ellipses (irises, orbital socket). I made the eye socket on the right side thinner, changed proportion of lip sizes. I tried to use as much of your own drawing as possible. you are right that a lot of rendering has taken place and that shifting proportions now would be a lot of work. It could possibly be done on this one or if you prefer try a second version. Hope this helps. Good luck!

(I'm not that good, take everything with a grain of salt) I think adding more values can help to push the forms a lot more. Kinda interesting to see that in your progress, in the first one the chin is blocky and masculine, but the shading then rounds it off. For example her upper lip is a tilted plane and becomes quite dark where it meets the lower lip. I think this is especially true for older people, so shading there could add to it. But of course the whole piece is pretty good as it is, if I had known how old she is by now I would have recognized her...

@Nicole Lee this is the reference photo.

What bugs you about the finished work? And are there examples of the style you're going after? It looks unfinished to me but it could be of a certain style that I'm not aware of.
