Kensington Palace announced the winner of the Duchess of Cambridge's Royal Garden Competition on Friday morning with a series of new photographs of the royal's work.

The palace released new footage and photos of the duchess' work with the competition, one which showed the duchess taking in the sculpture during a surprise appearance to launch the "Back to Nature" Garden on Sept. 10, and another of her judging the submissions on July 10, the same day she stepped out with Duchess Meghan and their kids for Prince Harry and Prince William's polo match.

"Oh wow, look at it – it’s amazing. It’s enormous," the royal tells Jessica in the video. "It's going to be so lovely coming back year after year to see how it's growing and all developing."
