Highlights in colored pencil

Here is an update on my colored pencil portrait work in progress. In the past, I used many dark colored pencils for not only shadows, but also highlighted areas, using a light touch. For this portrait, I am using more light colors on the light side of the face, and finding the whole process a lot easier and smoother-looking. I just try not to go too light too soon, or else really bright highlights do not show.
