Concept Art Colour Theory

Recently we had a lecture on colour theory, and at the end we were given a task -

'How have they balanced the colours? Consider colour proportion. Consider saturation. Consider temperature. Consider values' 

This character design on the most part consists a lot of greys over the armour, but what makes those greys look good is the highlights of very light blue and green where the light is reflecting. To also balance it out there is a prominent area of blue/green behind the character with its cape, underneath its head, top of the boots and over the crotch. This all allows for a good balance of greys and blues/greens throughout the characters design.The armour is very desaturated compared to the colours of the cape especially, and the area of colour on the cape is much more saturated and larger than the rest, meaning its one of the first things you notice. Its a very cool picture, there are no prominent reas of warmth at all, though the armour has a tint of red that contrasts with the blues.

This colour is very desaturated in this piece, using only one prominent light blue/grey area of colour. The foreground and the character are very darkly lit, comparing to the background where the sun seems to be brightly shining on the rocks ahead. This makes the character and the bird very prominent in the scene, as they stick out over the lighter background. Darkness of the character is almost reflected diagonally by the light area in the background, which makes the drawing seem to be symmetrical in composition.

This image uses opposite colours on the spectrum, orange and blue. This works really well for a huge amount of contrast in the image, with the lighter blue areas being the cooler feeling parts of the image, and the oranges / bordering on reds being warmer and where more of the action is happening. The character is in the upper center area, near the red areas. The image to me feels a bit cluttered, I never know where to look at first.
