Texture exploration

As my concepting work is coming to an end I am set with a task to start texturing the game level. As I am more of  a 2D guy I wanted to make my life easier so I quickly drew those building examples that could give me and my team some idea of some of the textures we could have. I bounced from many different types of buildings. Majority of the buildings that I have done have a modern look to them (full of lights, glass construction), but I have also included more of a destroyed looking buildings because we decided that we wanted our level to have a post-apocalyptic feel to it. 

To produce these I have used a simple perspective method. I created a cube in Photoshop and later on I applied textured on top using skewing to align textures with the cube.
