As a tribute to the moonlandings, the astronaut sculpture is fine. If, as the article states, the sculpture is a tribute to Buzz Aldrin's moonwalk (Apollo 11), the artist has made a glaring mistake. The red stripes on the spacesuit did not appear until Apollo 14 (they were used so that mission control could distinguish between the 2 astronauts.) Even if the stripes had been in use on Apollo 11, the astronaut in the sculpture would be Neil Armstrong, as the commander of the mission was the one who wore the stripes. None of that detracts from the process, which is admirable... but sometimes the devil is in the details (especially in art that commands 6 figures).
