Looks good to me.
Looking at that Atlas tractor, I see one of my few pet peeves about Atlas. Those rear axles have way too much side play! If you plan to use them without trailers, and take pictures, you might want to add a washer on each side, behind the wheels, to keep the wheels centered. Mine were made from styrene sheet, mass-drilled with a motor tool, and punched out with a 1/8 inch diameter hand paper punch from the office supply store.
