As a member of Emojination, I have designed around 160 emojis for proposals to the Unicode Consortium (the group that oversees and approves new emojis). Some designs have received a fair bit of press, including the hijab, woman’s flat shoe, and one-piece swimsuit emojis.
After an emoji proposal is approved, my mockups go to designers at the different vendors (Apple, Google, Twitter, Facebook, etc.) to use as guidance. These designers then create their own emojis to fit in with their style and platform.
As of January 2019, about 70 of the emoji proposals I’ve designed for have been approved by Unicode, and half of those are already available for you to use on your emoji keyboard. Below is a sampling of the emojis I’ve designed. If you have an idea for an emoji proposal and need a mockup to go with it, please feel free to contact me at firstname.lastname@example.org.
