More research on illustrating a scene 2

Similar to my last research, i am looking for ways to create that relationship of tones and shades of color. What interested me here is the figure in this illustration which is in a red hooded cape. The rest of the piece is a green shade and the red cape adds a interesting focal point for the viewer.The flash of red give the illustration more life.

For my own project i have contacted The Secret World developers for tips. They have gave me very useful advice " In general mid values should shift slightly more saturated. This will breath much more life into your colors." - Lead developer (username: Tilty)
This is very interesting and useful point, and from looking at videos such as the one above i got a sense of what Tilty was referring to. This is helpful to create more flow for the eyes which is important in creating successful illustrations.
Ofcause i am still focused on improving my technical skill at the moment, color and light is the main elements i need to practice to understand.
