Both the Stryker and Challenger look pretty descent; but I did notice a couple things...
1. In the third picture from the top the Stryker is "leaning" as if sitting on flat tires.
2. Also it doesn't look like any painting was done to the shroud on the TOW launcher or on the water cans. That may just be the lighting in the shot though.
3. On the third and four Challenger pics you can see a brush bristle on the left (as you look at the pic) track. It also looks as though the right (again as you look at the pic) track is twisted a little off from horizontal.
You're definitely getting there. I think the paint job on the Challenger looks really good and I like the weathering on the Stryker.
