The first picture shows the skins overlapped with both holes nicely finished. The large circle is for passing of the brake line to the wheel and also had to be cut into the forward skins.

The fuselage floor skin is the widest skin on the airplane and it just fits into the dimpler, as can be seen in picture two.

Then there are  a number of things needing to be done to the skin including adding some nut plates and stiffeners as seen in the last two pictures.
