you'll need face paint! I'm using Snazaroo, which is water based.
First, using your fav color, make a slanted triangles that go from your eyelash line, up toward your temple. Also, paint on a muzzle by your mouth with an oval shape. Be sure to cover your top lip!
Next, paint an outline around the muzzle, with the line being thicker closer to your mouth. Also, draw a wishbone shape up by your eyes, with lines connecting at the inner-corner of your eye.
Add some teardrop shaped strokes on the outer part of the triangles. Don't forget to draw a line down from the bottom of your nose to your bottom lip. This will split your lip in two, like a cats.
now paint a little pit of a pink(or black) nose on the bottom of your nose. Cats have a small nose, so don't go overboard!
Also, make some whisker marks, they can be stripey(like on the left) or dottie(like on the right.)
now, outline your eyes in black, and add some more flourishing lines. You can also add thin white line for whiskers, and tiny white triangles on your bottom lip for fangs. Don't forget to color in your bottom lip!
