Great start but (as AsaNYC said) re-UV the signs so that they're correct, it'll be a big step. I know it's already pretty grimy but it could use some more detail--some unique dings and scratches, not just cloud noise.
You can clearly see the damaged metal near the big edges that draw our attention. The green metal rust is brown colored, and there are several tones of grey and green in the texture.
The grey and green color of that texture is still in 'range' of eachother but you can clearly see the difference between the different parts of the model.
I think ur dark green and grey are too close to eachother. If you were too look from a distance there probably won't be any difference. Some work in the texture will really improve this model. Also try to keep in mind how ur texture would react with a specular to show off the details
Thanks for the post It's a great example of how a spec map can help make a metal object look more metallic. I do have a spec map on this model, however after viewing the pic from above I realize I need to boost it up more. I really like the scratches along the edges on that trunk as well.
