The World of Trompe-l'œil (pronounced in French as "tom play")

Hi,
Since I have set the assignment, I can bend the rules. Instead of posting 1 image, I have greedily posted 5.
Always a fervent lover of street art for its activist spirit, these pieces of street art never fail to impress me.
Why are they realistic?
1) They trick the eye with the "trompe l'oeil" technique. According to Wiki, this technique creates extremely realistic imagery in order to create the optical illusion that the depicted objects appear in three dimensions, instead of actually being a two-dimensional painting.
2) They depict real-life elements -- e.g. humans in correct proportions, the coke bottle and laptop
3) The humans' expressions are not exaggerated or set up in theatrical dramatic ways.
4) The contrast of light and shadow used is apparent especially in that of the coke bottle.
5) The monumental scale of the floor painting allows one to be fully immersed in the experience of viewing the work.
6) It duplicates reality as close as possible.
7) It invites interaction because of its impressive scale and realism in the technique.
8) It creates the possibility of another world by transporting us into the creation of another reality (which is one of the main functions of Art)
9) It does not defy gravity.
10) The rendering of the water is extremely realistic with the transparency created.
