Blender Cycles, 400 samples, without compositing.
The scene is made of:
-Grass (from BlenderGuru’s Grass Essentials pack) and a tree from BlenderSwap in foreground.
-A plan with a Glass material with an IOR of 1.33 for the water and a boat from BlenderSwap.
-A background image imported as a plan from Cgtextures.
Comments and critics are welcome.
