My work mate is busy with setting up the skin so I have come back to finish up this beast. I will add all of the bolts and rivets as a displacement map once I get all of the textures finished up on the exterior. All the textures are very flat at the moment as there is just a color map on a lambert shader.
I really appreciate the comments and your criticism on this guys and will do my best to make adjustments and improvements in the suggested areas. It has all been noted and time provided I will go back to make improvements. I am likely to go back and re work on the hummer 1st as I feel it still looks very weak and will get some more ref images at work to try and improve things. I then need to add texture details to the chinook before then looking over weapons and finalizing character textures.
