I've grown impatient waiting for Sombra's character reveal, so I decided to design my own.
I took inspiration from the Spanish looking woman in the official Blizzard shot of old Overwatch team members. I used her armor and hairstyle, plus the Sombra logo and the purple color she uses in the ARG.
I also remember reading about an idea the devs had for a whip based character, so I thought it would be cool for her. Maybe she uses it as a cable to jack into Omnics from a distance?
