1) The color of the upper chest doesn't match the rest of the Body (regarless of lighting). You can see the color change where the shoulder meets the chest on both sides, as well as where the neck meets the chest.

2) The body shine also doesn't apply to the upper chest. Again, you can see a clear cut-off where the shoulders and neck meet the chest.

3) There is also slight clipping on the lower chest when the chest is completely minmized.
