In my Odd'l Rockets kits I include "Extras" or practice decals. Start with those smaller extras first! It's tempting to apply the largest, most colorful decals but save them for last after you get a feel for the decal soak times and how they transfer.
TIP: Always wet the surface of the model with a wet finger. Rub the water back and forth and leave on the surface.
This gives the decal some surface lubrication and lets you position and re-position the decal until it is where you want it.
Obviously you include the word Goony on the decals. I replaced the stylized eagle with a duck. The duck wasn't part of the first Goony F-16 build, the decal was changed after the model was finished. The center star was changed to a target with cross hairs.
The CAUTION decals made me think of things my Mother would warn me about.
Some of the references are a little inside like the number on the rear of the rudder decal.
The DANGER decals near the canopy were changed to DANGME.
