Sometimes the difference between a good model and a great model is in the details. When adding stowage think about how its going to hold on. Jerry cans should be in racks or tied down. Tarps, bags, boxes need to be secured. Extra wheels, pieces of track also need to be attached - welded bolt through a lug hole, welded strap across the track.
I know its not an earth shattering subject, but I just won a best of show against this and other modelers primarily because my stowage was realistically attached and not hanging in mid-armor...
