That looks fantastic. Is this for an Armies on Parade board?
Yeah dude, For my white tau army. Going to muddy them up good.
what colors did you use for the brown mud?
I use vallejo air colours that you can get from most model stores or amazon. they are far better than GW colours and cheaper too. http://tinyurl.com/pvtrvjmAnd the colours are, Mahoganny, Olive drab, Dark Brown, US grey Camo, Dark green, Russian green and Camo Grey Brown.
