Diversity in Landscape Textures

Now that a few buildings have been added to the level, the scene looks slightly out of place because the entire ground is grass. To combat this, I created a second landscape layer and dragged it slightly above the original to create another stone ground area. The material that I sourced was off of a website/blog called Free 3D textures and the author was Oliviier French. A link to the texture is bellow:
