These photos prove one thing: The cosmetology students at Denver Public Schools’ Emily Griffith Technical College have skills. Like, crazy skills.

Like, they’ll amaze you, gross you out and make you feel bad that you cut two holes in an old sheet this Halloween and called it good.

For the third year, the college students in the 11-month cosmetology program at Emily Griffith — which is the only post-secondary school in DPS — have used their hair, nail and makeup-application savvy to transform their classmates into the undead. (Watch a video of the process below.)

Emily Griffith is hosting a contest for the goriest zombie. Anyone and everyone is encouraged to vote for their favorite zombie via this Facebook post by liking that zombie’s photo. The voting continues through Friday, and the three zombies with the most likes will be announced on Nov. 14.

Here’s a sampling. To see all 17 zombies, visit Emily Griffith’s Facebook page.
