So yeah, you could do muted browns, pale greys, desaturated khaki tan colors, terracotta reds.

Small detail ideas:
If your stompa walked through a building, aside from dust there might be bits of construction stuck on certain flat surfaces (look up "killdozer" images for examples of this).
For the feet: trash, food wrappers and squashed cups stuck to surfaces and crevices.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/763935/10154679.page http://www.dakkadakka.com/dakkaforum/posts/preList/763935/10154679.page GMT FW or Flames of war or ebay; done at the last step after you've finished painting, sealed with sprayed matte varnish.

Flames had 'European dust, concrete' which are viable, FW have light brown which is suitable.

EDIT: dry powders achieve effects you cannot otherwise do with painting, very easy to apply, simple apply desired areas with a dry brush tip, blow/brush away excess, I typically do it around the boots, lower end of long coats, exhaust tips, muzzles, tracks, etc. ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/763935/10154684.page http://www.dakkadakka.com/dakkaforum/posts/preList/763935/10154684.page GMT http://www.dakkadakka.com/dakkaforum/posts/preList/763935/10155116.page http://www.dakkadakka.com/dakkaforum/posts/preList/763935/10155116.page GMT
