GOW_LAV Tank Texture Blocking.

Yesterday I started the task of texture blocking my GOW_LAV Tank concept, my main focus to add a cool camo pattern onto the model and strat to get some colour in there.
My next task will be to add some nice bumps, displacement and dirt to the textures before the final pass.
Also a quick note on the default VRAY HDRi sky background; I'm thinking of rendering an alpha pass so I can include a matte painting/ photograph behind the image of sand and tank. For now here is my latest progress.
