Australian artist Matt Doust died in the U.S. after reportedly having an epileptic seizure. He was 29. The artist was about to debut his art exhibition in Thinkspace, an LA art gallery.

"Our hearts go out to the family of Matt Doust who left us all much too early. Sadly Matt battled epilepsy his whole life and a bad seizure took him from us sometime yesterday evening," Thinkspace posted the following tribute on its Facebook page on Thursday.

The Perth-based, American-born artists' U.S. exhibition was due to open on September 7. However, the gallery will go ahead with the exhibition despite his death.

"We hope to be able to have the show still take place as a celebration of Matt's life and work and to all come together and just honour what an amazing soul he was," the gallery officials said.

Doust is best known for making portraits of celebrities and his portrait of Perth model Gemma Ward was shortlisted for the prestigious Archibald Prize in 2011. He moved to Los Angeles the same year and had noted Hollywood celebrities amongst his customers including comedian Jim Carrey and Oscar nominee Mickey Rourke.

Doust delved in portraying his subjects to the minutest details to capture the expressions and emotions of the person.

"Doust's dramatic human landscapes tap into the subtle revelations of physical expression, drawing the viewer's attention to the subject's minutest details," according to a press release of the exhibition.

"Doust captures what stirs beneath the skins of his subjects. With great technical facility, and a genuinely unparalleled refinement and detail, he is able to animate an inanimate surface with an evasive internal life," the release added.

"Doust draws on our anxiety and fascination when faced with the other in this unfamiliar proximity and scale, forcing monumental disclosures of intimacy upon us. At times voyeuristic, these larger-than-life portraits are both alienating and intimate."

An autopsy is being conducted to determine the cause of death. Check out the artist's picture gallery to remember what a great talent he was.
