Macro photography is always about photographing really small things, such as insects, small flowers etc. It can also be used for fun things like photographing childrens toys, such as Star Wars Figures, be they from the Lego variety or action figure variety.
For this shot, I placed a sheet of A3 paper on my kitchen worktop, had my 50mm Sigma macro lens mounted, and my Nissin di866 Pro MKII flashgun.
Apart from bringing the inner-child out in you, its great fun coming up with different ideas. If you google “Stormtrooper Photography”, you will find thousands of inspirational photos to have a look at.
