Study of light

For this part, I simply have to analyse a painting about its light, and for this I chose a 3D model called "Celebration" by an artist on DeviantArt called Drea Horvath (or "00AngelicDevil00").

As you can see, the first immediate light sources are the Chinese lanterns on the water and floating off into the distance in the sky. They are each their own light source. The paper of the lanterns also bounce the light around inside, sub-surface scattering, giving the objects a soft orange glow, iconic of the product. Additionally, you have them all reflecting off of the water, which I think is specular reflection as the light is reflected directly at you. You also have another light source coming from the tower, presumably multiple sources from each room. Considering the colour of the light and the fact it seems to be lit by fire (judging by the colour and comparing to the visible light sources) I would take a guess that this is all bounced light, diffused reflection off of the surfaces of the surrounding walls. Finally, in the right of the image where you have the cooler blues in contrast to the warm red lights, the sky is lit up in a moonlight blue. The clouds are clearly visible and completely blocking the night sky, but due to their glow I can assume there is more bounced light inside the clouds which gives a soft light across them and again reflected on the surface of the water. Because of the distance of the objects and no land or anything similar in the foreground (which would probably mean the camera would be in the centre of the lake), there is no visible objects under the surface of the water.
