更新1: good idea!
i think u can draw an earth as background
while use different people with different nationality as the main theme. like drawin an indian shaking hands with a Dutchman and the background with the Paris Effiel Tower or other countries' landmark building e.g. Pisa Tower
White house e and of coz draw more differnt people with different skin color
different clothings like some wear japanese kimono while others wear korean clothings and with different cultural decorations e this would show that people from different parts of the wolrd join together and share each other's culture within globalisation. Hope this helps
I think you can draw the earth. and then you can draw some people on the earth that is (very huge) can show us the world is very very *** all .
