The sculpture features a collection of butterflies crafted from recycled aluminium drinking cans.
Judges Tony Jones and Connie Petrillo praised the artwork, labelling it “poetic and elegant”.
Takahashi was not the only winner, with Applecross Primary School scooping the $500 Schools prize, and Olivia Samec and Frontier 3D’s piece Infinite claiming the highly commended prize of $1000.
The collection of 26 entries transformed the Heathcote site into a temporary outdoor art exhibition, with sculptures and installations from WA artists, Tafe and local school students.
The Sculpture Walk closes on Sunday, April 3.
Visitors to the exhibition can vote for their favourite sculpture in the People’s Choice Award, which will be awarded at the end of the event.
Voting slips and further information is available onsite at the information stand.
