First you draw the circle, than it's easy to align an emoji, draw the face and It's done. Feel free to combine the eyes, and everything. I also added some small other symbols.
I hope you like it.
Please note this is a remix the emojis are from this model.
The author remixed this model.
I added a circle to easily draw continuous outline for the faces, added some small symbols, and it's a bit smaller with less emojis.
