This is my first Exterior Scene. I'm doing mostly interior scenes and I wanted to try something else. To make the effect of tree shadow you will need to make your own tree. I haven't attached the tree itself, because the file with the tree has about 140mb size and without 40mb. Feel free to use any object u find on the scene to ur project without asking for permission. Please let me know what you think about it.
I have one tip, try giving the sun light more intensity and give it a slightly yellow/orange tint.
