Absolutely Friendly Critique: From examination of all the models I've acquired --- I agree Good Weathering is very difficult -- looking at the progression in SLI/TrainSimulations models and Diesels West models...one can quite easily spot the early weathering efforts vs. the later ones...much more realistic. Knowing nothing about this ( except coming from an art perspective -- MA in photography ) -- try less precision, more "smudging" -- more of an "accidental" application -- if that makes any sense. Again, just fine work on the models...and of course the most excellent cabviews.
