"Big Walls, Big Dreams" is a collection of walls in Wynwood, curated by UP Art Studio, and painted by 15 artists from around the world during Art Week Miami 2015. Artists include Shalak and Bruno Smoky from Toronto/South America, Enrique "Sero" Cruz and Ray Jafete from Miami, Inkie, Mr. Cenz, Lovepushr from England, Jay Mack "Muzik" from New Jersey, El Pez, Zosen and Mina Hamada from Barcelona, FPLO and Graphis from Brazil, Eelco Virus and Mr. June from The Netherlands, Brusk DMV from Paris, Dread from Denver, Colorado, Mas Paz and Che Love from Washington, DC, and Nicky Davis and Wiley Robertson from Houston, Texas.

The centerpiece mural for "Big Walls, Big Dreams" was "Free Lolita". Painted for Mayor Philip Levine of Miami Beach, the purpose of this mural is to bring awareness to the campaign to free Lolita from the Miami Seaquariam following over 40 years of captivity. This mural garnered massive media attention including TV coverage on CBS, the front page of the Sun Sentinal, tweets from Pamela Anderson, PETA, and the Orca Network to name a few.

The artists, Shalak Attack and Bruno Smoky, a collaborative duo (husband and wife team) also known as Clandestinos. On the same building, located at 2247 NW 1st Place, an additional 12 murals were painted. Additionally, Mountain Dew commissioned two murals for Art Week. The first was to commemorate the partnership with Miami Heat and basketball player Justise Winslow. The second was less commercial, with UP Art Studio as the subject.
