Alberto Giacometti

Son of post-Impressionist painter Giovanni Giacometti, Alberto Giacometti; died in 1966, was a Swiss painter, sculptor, draftsmen and print maker. Most well known for his award winning sculptures of tall thin silhouettes, Giacometti has also series of expressive portraits. 
His style of drawing is very suggestive using loose lines to create tangled, yet structured drawings and with the use of light and tone he has added depth to certain drawings.
I like the use of tone in some of his drawings and how the use of black lines have been used to define detail yet still in fitting with the abstract and almost experimental style of the drawings. On the other hand some of Giacometti's simpler drawings, I do not like because of the lack of depth to them, I feel that his drawings with more tone are stronger and have more of an impact as a drawing than others.
