Students were tasked with designing posters to encourage an alcohol-free lifestyle for youth.
A judging committee nominated 15 semifinalists, and then local artists and online voters chose winners in each of three categories - elementary, middle and high school.
More than 4,300 people voted for their favorite poster and artists including Ilene Adams, Trina Slade Burks and Rolando Chang Barrero of ActivistArtistA gallery at the Boynton Beach Arts District made the final decision.
"We have to compete against alcohol companies who can spend millions of dollars advertising for those kids' attention," said Alexa Lee, program director at the Substance Abuse Coalition.
"I think it's really important for them to see a positive message about being alcohol free."
The elementary school winners are Breanna Sandoval, a kindergarten student at Pine Jog Elementary school in West Palm Beach (Critic's Choice) and Trinity Suma, a fourth-grader at Manatee Elementary in Lake Worth (People's Choice).
Marissa Suma, Trinity's mother, said, "Trinity loves creating art and wants to send a good message to the other students."
A student in Jennifer Robertson's Discovery Lab, a class for gifted students, Trinity, who loves math and "Wump World," an environmentally-themed children's book, was inspired to create her poster of an astronaut from one of her lessons.
The astronaut, standing on top of the earth, is saying, "I feel out of this world to be alcohol free."
"It's fun to be in a contest," she said. "I took a shot at it."
Middle school winners include: Sabrina Roche, a seventh-grader at Palm Springs Middle School (Critic's Choice) and Grace Wiley, an eighth-grader at Independence Middle School in Jupiter (People's Choice).
High school winners include: Anthony Marcos, a 10th-grader at Spanish River High School in Boca Raton (People's Choice) and Deondra Pink, a senior in the South Tech Academy arts academy in Boynton Beach (Critic's Choice).
Pink, a first-year student in the academy, is a former cosmetology student who transferred to the graphic arts academy.
She hopes to go on to study psychology at Palm Beach State College.
Her winning poster," Your brain will fart, if you don't act smart," resonated with other students and with the judges.
"Who doesn't love a good fart joke?" said Adam Fiveson, the graphic arts teacher at South Tech.
"While others may show a finer execution, Deondra is one of the cleverest and other students will relate to it when they see her poster."
The top six posters and title sponsor winner will be displayed on 900 school buses in the school district.
Also from South Tech is 11th-grade student, Bradley Cash, who took the sponsorship choice by title sponsor, the Hanley Center, a drug and alcohol treatment center.
