theShadow, cool textures, but there are a few things you could do to push it further.
One is to add some slight colour to all the gray. I don't mean make it pink or red or blue or whatever, but to add just a hint of colour to it. While it'll still be grey, that extra hint of colour will make it more alive. Completely greyscale colours are dead colours. Perhaps some brownish rust, to add quality to the (currently black( wear and tear.
The other thing to do, is to make the red stripes more prominent. The bland effect they have right now contributes to dullness and not liveliness of the texture. But perhaps this way the goal.
And the last thing is to is to add a specular map. These make a huge difference in the final overall appearance of the texture. Perhaps you already have this planned, but I thought I'd mention it.
Overall the texture is good but has a lot of potential left and with some additional work, it could reach it.
