As you can see, I've gone with the local highway patrol car as inspiration for the base with a star indicating the figures forward facing.
The stars are done pretty simply, with a dot of bronze coloured metallic paint...then I cheat. I draw the star over the top with a fine marker pen. When preparing a dozen bases in a similar manner, sometimes a shortcut like this makes the process a bit less tedious. The downside is that you need to spend a bit longer before clear-coating or spray varnishing the marker ink, otherwise it's prone to running.
