This piece was completely constructed by using a black inkpen in the style of pointilism.
Pointilism is a technique whereby the very tip of the inkpen is dotted onto the canvas, creating the tiniest of dots and built upon to create the figure of the male model that you see in the finished piece.
To produce this type of work from start to finish takes many, many painstaking hours.
The effects which can be produced with pointilism can be delightful and intriging.
If you do choose this artwork as a piece to hang on your wall or to give as a gift, I recommend choosing a black border or mount for this, as it will trully complement the ink work.
