I can help you make a clear beautiful grey material render,of course if you want. 
At first it's too early for textures.
Use standard scanline render. (Ideal for WIP)
Place omni light somewhere near the model. Next place skyligt above.
In render settings go to Advanced lighting and select Light Tracer.
Render image. The result will be surprising. :)
For example - here is my old render with advanced lighting in scanline.
