Llewellyn's photo students from the Class of 2013 said projects like that have even made other people jealous of Edgewood.
Summer Howard said she knows people at other schools who wish they had gone to Edgewood.
"They all think Edgewood is really awesome now," she said. "They think we are this awesome school that does awesome things."
Matt Thomas noted his classmates spent their first year of high school in the old building, which had more negative associations.
The mural project "is a lot more positive view," he said.
Nick Huppman said a lot of people have posted the portraits on Facebook, and Summer said some residents and parents have commented on the portraits as they drive by.
"We are a wonderful community and more people should realize that," Summer said. "It's a great way to express ourselves through art."
Llewellyn said the different faces, which include seniors in their caps and gowns or making grotesque and silly faces, make fun of the Edgewood stereotypes.
As Christ explained: "When you put a face on it, you can no longer say, 'Oh, that's Edgewood, that's Route 40.'"
Christ also said the project shows the collaboration that goes on at the school.
"This school is blowing up when it comes to the arts, as far as how distinguished our photography program is, our dance program, our theatre arts program," she said.
Patricia Nelson, who owns Creative Journeys Child Care right behind the mural, was impressed when she walked around her business to check out the finished work on Tuesday.
"It was awesome," she exclaimed, adding she had five children go through Edgewood High.
"It's nice to get positive attention," Nelson said about the mural. "That is positive attention, because with Edgewood High School, it's always negative."
With the help of social media and community outreach, Llewellyn said there is no stopping Edgewood.
"That is why a project like the Inside Out project makes so much sense for us, because we are turning the walls of the school inside out," he said. "We are imposing what the school's reputation actually is."
