Cho Chang famously gave Harry Potter his first-ever kiss – but the actress who played her has one major regret about the momentous scene.

“I wish I never cut my hair the way I did,” Katie Leung told PEOPLE on Friday at Universal Orlando’s three-day Celebration of Harry Potter event.

“I had this horrific haircut!” she said of her look as the shy Ravenclaw in 2007’s Harry Potter and the Order of the Phoenix.

But that’s not the only thing she would change about her run in the Potter series.

“You grow as an actor and you change your choices,” she says of shooting the decade-long series. “That’s partly why I can’t watch them. I’m just really judgmental of myself.”

Leung, who first appeared as Cho in 2005’s Harry Potter and the Goblet of Fire, says that as a young actor, nothing could have prepared her for the breadth of the production.

, which runs through January 31, include Rupert Grint, Evanna Lynch and Matthew Lewis.

Wright posted a picture of herself alongside Leung and Lynch, wearing bracelets Harry Potter-themed bracelets gifted to them by J.K. Rowling.

“Thank you @jk_rowling for our @lumos bracelets,” she captioned the snapshot.

West coast fans may be soon getting their own chance to enter the Potter world as Universal Studios is opening a themed park in their Los Angeles location.
