How the FUCK???

How the FUCK!! do these people do these chalk drawings? Where do you start? How do you get the perspective down so freaking well? Mind blown by these, everytime I see them.

Hyper-Realistic Acrylic Body Painting...

When I first saw this I though :-S, so what, some photoshop'D pic of a painting put in a real world setting. But it turns out its a dude painted to look like a canvas painting. Really amazing stuff. It was all done by an artist called Alexa Meade.

Most artists use acrylic paints to create portraits of people on canvas, while Alexa applied acrylic paints on her subjects, and made them appear to be part of a painting.
