I can't really chime in with my 2 cents worth of criticism, because there's not that much wrong with it.
I really like te overall look of the paint. I think it really captures the appearance of a weatherbeaten vehicle. The tools with thier wooden handles look excellent as well.
My only quibbling point, worth 1/2 a cent or so, is that the rubber on some of the road wheels seems a bit too black in the photos. Maybe a light coating of dust might be in order.
All in all, an excellent vehicle. Can't wait to see it when it is finished.
