I have grown very fond of the work of fellow Puerto Rican artist/muralist Alexis Diaz. His work is beautifully created with very intricate crosshatching and traditional art making skills. It is unusual for a street artist nowadays to use this kind of skills as a way to stay on par with the street art scene.
His murals are focused in the organic. Usually it is a combination of different parts of animals or people. It gives the sense of an old anatomy or science book illustration. Alexis Diaz now have murals and commissions all over the world.
