The art -- 'Mahatma Gandhi sculpture for non-violence and peace' -- was created in the contest in Moscow in April this year. After the competition, an exhibition is being held there since then.
Pattnaik's sculpture has got 60,000 votes out of the total 80,000 votes from the visitors to the exhibition, according to a letter by the event's organiser Pavel Minilkov.
"It is a really a pride moment for me that my sculpture is liked by so many people," Pattnaik told PTI.
Pattnaik has participated in more than 50 international sand sculpture championships across the world and won many awards for the country.
He was honoured with the country's fourth highest civilian award Padma Shri in 2014.
Pattnaik runs a sand art school at Puri beach in Odisha.
