I think you've done great weathering on this build, and really love the little details like how you've 'wiped' away the dirt from the windows and rear lights...it brings so much more life into it.
And how you've managed to crack the windscreen is pretty impressive. If you cracked it by accident...very nice recovery by making it seem deliberate. If you cracked it by hand....I'm very impressed with the skill it took, not to snap the entire window in half! Great stuff!
