Moto and Candy portrait in progress 8

Now I’m starting on Moto.

I didn’t finish Candy’s body because their shoulders are overlapping, so I want to do both of their chests at the same time to get the color tones and values (lightness/darkness) matching. Since they are done from two separate reference photos, taken at different times in different lighting, the colors (for example their rust markings) are not the same in their photos.
