Well, this is the final masterpiece of my portrait as a machine! Originally, this is a Dancing Machine - because I am now mostly interested in the dance sports (though I'm not really a good dancers! :( ') Uhm, I try to work with as many colors as possible initially, then I found it's quite "ugly", so I decide to use only black and white for grayscale and the RED color for some parts. This was base on the shape of my face in the lower portrait!
