Twiggy portrait evaluation

The good point of my portrait is that I have used tone really well to bring out certain features such as the make up,the jaw line also the patterns on the jumper. Everything is in the right proportion and the sizes match each other like the eyes and the nose size. I have used the grid method well meaning that my picture has come together well and all the lines and dips are in the right place. The outlines of the face meet in the neck and the jumper meet in line. The eyes are also level following the lines. An improvement is about my toning on the face the lines of the tone show so I will need to blend it in to make it look like the shading has gone in one direction. I need to use more tone around the nose as it look flat and there is a higher structure to her nose. To do this I will do harder shading to make the nose look 3-D. On a whole I am happy about the way the 'Twiggy Portrait' has turned out well.
