Future Subway Unwraps

For the subway I have tried to make use of texture space by including as many assets as I could on one sheet. For the entire scene I only used 4 colour maps and 4 of each other respective maps (e.g. Albedo, Specular, Normal, Emissive, Ambient Occlusion) All the textures were then made using Quixel with exception of the floor tiles, in which I made a more high poly asset to bake using xNormals software.
