Seldoon, that animated example you gave isn't adding contrast, it's adding light. Contrast is the difference between two things. In the case of mapping it usually means light (intensity and color) or textures. What you've done is brightened the scene and then changed the tone of the color. Your example isn't wrong, but we should be clear about the definitions of terms so as not to be confusing.
As others are saying, it should probably be a little brighter, but I think the warm colors outside are great. They suggest warmth, which is what I think of when I think jungle. However, inside the ruins I agree with the suggestion of cooler colors. The inside is clearly damp (water dripping everywhere) and should be lit cooler. Give the mental cue of a cooler atmosphere with cooler lighting, i.e. blues and greens.
