Overview

This is a LoRA that attempts to emulate the style of Josan Gonzalez (also known as Deathburger), a Spanish artist and illustrator renowned for his science fiction works in the cyberpunk genre. His style is characterized by high levels of detail, vibrant colors, and the use of the ligne claire technique. Despite the grim themes, his works are distinguished by their lightness and playfulness, often incorporating elements of satire. His art is influenced by artists such as Moebius, Geof Darrow, Katsuhiro Otomo, and other masters of science fiction and comics. His works attract attention with their unique combination of 1980s nostalgic aesthetics and a contemporary vision of the future, making him one of the bright representatives of modern science fiction illustration.
