Giacomo,
A really nice build and worthy of the MOM competition, may I make a suggestion as to a couple of things that might add to the look?
Firstly, if you make a slurry of some Mig pigments with some enamel thinners, then paint the mixture onto the steel wire, mask under it with some post-it notes, working it into the weave of the wire. Once fully dry, carefully rub the wire with your finger or a cotton bud, leaving the dust just in the weave. It will make it blend with the vehicle.
Then with the pigment that dries in the mixing palette once it dries, brush some onto that glaring head lamp, to dirty the lens a little.
Hope you cont mind me making these suggestions but those bits stick out like a searchlight at night.
I can show you the effect on my T55

Good luck,
John
