This is my texture and render progress over the weekend. I start from using contrast of orange and blue to stand out the objects and background, but it didn't make sense for a safari environment with the cave painting style we are going for, so I re-do the texture and the colour. Also safari should be a open space and wild environment so I scaled the background and move the sun more backward, gave more depth for the scene by adding trees at the background and extend the river.
At this stage, I am not sure about the grass should appear like this because we want to create a scene with long grass around the whole environment, but it looks messy and lose focus of the scene and also if I do that it is going to take long time to render after putting our characters and animate them. So I am going to try another way to do the grass, which texture the plane with fur presets and attributes and make it in layers. I am going to do some tests before I put it in the scene.
