Unity 3D + Graphic Novel + Panal Setup

All assets are being created in Maya and Unity 3D. I created this 25kx25k terrain mesh in Unity, All assets in Maya and Textures in Photoshop + Bitmap2Material. This is the Crystal planet that orbits the main planet in my book. I'm done modeling the crystals, and all I have to do now is texture them. The terrain skin will have crystals everywhere which will be explained in my story. There will also be vegetation, large rock structures and other objects placed everywhere when it is finished. This will be used for concept art and line drawings. I will be making videos walking on this world for advertising purposes.
The texture set is finished for the most part for this terrain. There are 8 all together, I will not be using PBR workflow for this project, it is not needed. I enhanced the Diffuse and Normal textures with more detail. All textures were created in Photoshop + ZBrush and then ran through Bitmap2Material to further
I'm creating the worlds so I can get better panelperspective.
