Fields' artworks explores the themes of family, community, and cultural diversity to illustrate its significance in societal norms for Native Americans.

Fields' techniques involve using oil, acrylic, and watercolour mediums on canvases and paper to create his works of art.

“I saw on a global scale what artists were doing and the dialogue they were having, and that shifted my perception of what I wanted to do.”[4] In 2000, Yatika attended a college-level summer painting course in Italy, which was organized by an art professor from Oklahoma State University (OSU).

[1] In November, he presented himself at the APEC Economic Leaders’ Meeting where he was chosen to represent young Native American artists.

It was me finding another new voice and new style and rejecting everything I had just learned (in college),” says Fields adding that his graffiti work added to his ability to work large-scale and use full body motion are skills that he continues to utilize when creating large murals in front of an audience: “It’s almost choreographed, like you’re putting on a performance.”[4] The use of strong and vibrant colours in his pieces portray the diverse groups of Indigenous people.

He creates his art in these communities because he wants to brighten these sites with bold colours in order to show the beauty of that specific place.

Any young artist, especially Native artists, as long as they’re doing it right - right meaning challenging the perception of the work and working with their community - I want to help because I’ve been fortunate to get where I am today through the help of others.”[4] Fields was at Standing Rock in 2016 when he joined the Standing Rock Sioux Tribe and their supporters at the Dakota Access Pipeline, a major event in his life as an activist.

“My dad was at Alcatraz and we had family friends at Wounded Knee, so I’ve always known about Native American occupations and the politics of the United States,” said Fields.

The gákti is worn during ceremonies that are "characterized by bands of contrasting colors, a high collar embroidery and tin art"[7] Yatika Fields captured this moment to illustrate the realities of indigenous people.

[9] Fields’ mural is alive with movement and filled with images that rely on vibrant colors and swirling patterns to show drums, beads, dancers, and horses.

As any Native person knows who dances or participates in ceremonies, they understand that feeling of rhythm and place and movement.” That usage of movement and “swiftness” has since carried into his work, allowing it to flow from one end of the canvas to the other.

“Yatika was delighted to have the opportunity to paint a mural that will inspire Native American students at NOC.”[11] In February 2021 Northern Oklahoma College signed an agreement to display art works from Pickens Museum on their Tonkawa campus.

[12][13][14] In August, 2022, Northern Oklahoma College announced the transformation of Vineyard Library into a contemporary Student Learning Commons named the Pickens Learning Commons, that includes two new permanent murals totaling 100’x20’ by artist Yatika Starr Fields, along with eighty art works from the Doctor Pickens Museum to be on long-term display.

Fields already created two existing murals in the Cultural Engagement Center, commissioned by the Doctor Pickens Museum in November 2020 and completed in June 2021.

[15] Yatika Starr Fields' 100' x 20' mural in the Pickens Learning Commons includes several different scenes from Northern Oklahoma College including a woman looking through a microscope, show lambs, another woman looking through a stack of books, men in space looking through VR systems, NOC’s mascot, Mav the bull, the Roustabouts, and the different performing arts.

"[16] Fields runs Ultramarathons several times each year and in August, 2019 completed the Ultra-Trail du Mont-Blanc (UTMB) TDS, a 145-kilometer (90-mile) trail race in the Alps with 9,100-meters of elevation change.

His resume lists the following:[18] In 2000, Yatika Starr Fields received the American Vision Award after he graduated from Stillwater High School.

Yatika Fields and students from the University of Arkansas-Fort Smith (UAFS) painted what they envisioned when they heard an orchestral piece being played.
