He took Fine Arts and majored in Painting at E.A.R.I.S.T. in the early 2000s. Since then, he has been actively participating in different group art exhibits and is currently part of a Pasig-based art group known as Door305.
His art seeks mainly to portray the different passions of this generation and paints what he observes in his community, juxtaposing human pastimes and frivolities against reminders of mortality and sacred images of the Catholic faith. Arnel strives to imbue his contemporary art with social responsibility.
He is known for his poetic captions and titles, as well as for the colorful stories behind his paintings. He loves to intrigue his audience with his work and lives by his own words, "Life is a puzzle of stories, a palette of experience and a rainbow of excitement".
He loves to distort images in his artwork in a style called cubism, popularized by master cubist Pablo Picasso and locally by Vicente Manansala, that uses different colors, shapes and geometrical patterns. Using his own visual language, he transforms canvas into interesting pieces of art.
Arnel is now a full time artist/cubist signing his works as ARJANA (short for Arnel Jatulan Natividad) in honor of his roots.
