Green Dragon you look kinda complicated...
On my own opinion i see the greenish representation as a covering of an hut house which has been washed out slightly due to seasonal changes, thereby causing some amount of transparency. Due to transparency , we can ascertain that the Sun is responsible for the reflection.
I am almost comfortable with my observation. because if the greenish representation is properly looked at you will notice 4 major lines linking to a sharp point from the outside, I specifically called it covering because it has to be a material as a result of the stretches.
In order to be more comfortable i rather not talk about the red representation because the name of this photograph is called green dragon. Chuckles.
By the way nice post Mr Velimir.
