Steven Lopez is one of my all time favorite artists. He is notorious for combining traditional art elements with graffiti.His work is not famous but he is one of the most accomplished artists of all time in my opinion.
What I enjoy the most in his artwork is the artist's ability to combine abstract with representational images, creating a complex figures.Also, his use of color is just outstanding.
