Villagio Food Court, semi - final

At this stage I'm starting to chose which icons I would like to use as my final chosen 8 icons. And begin to finalize them so that they all look similar. However, my instructor has informed that if i chose to work with people for the icons, I should only use people, and if i work with objects then i should only show icons, and etc. and not mix those two things because it would be confusing for the viewer. Second she also advised that i change the color of the squares for the icons since it has been used so many times. And that i should do something different and unique. The color must reflect the food court aswell.
