This is my emoji, I used Adobe Illustrator to make it. I first a big X. Then I made a red, green, blue, and yellow circle (that image is shown above). Using these circles I made the face and the eyes. The red circle being the biggest served as the face. And, the green one was the sclera. The blue on was the iris, and the yellow for the pupil. Then I used the stroke tool to make the eyebrows and mouth. For the mouth I added more anchor points and a fill to get the shape. And added a gradient to the stroke for the lipstick. And, for the nose I drew it with the pencil tool. I also used the pencil tool for the hair.
