Start with a couple of squished circles and add some rugby ball shaped pupils inside them for that animal look
Between the eyes draw 2 lines dropping down to a slightly bloated triangle. Remember to add some nice black dots for nostrils.
Under the nose, draw a thin sausage and a couple of triangles pointing upwards for some ferocious fangs
Make some shapes with jagged lines above the eyes and under the mouth
Every beast needs awesome horns! Draw 2 pointy banana shapes just above the eyebrows and make them stripey with come curved lines.
Join the eyebrows to the beard with some more jagged lines running along the sides of the face
Go wild! Draw a bunch of jagged lines connecting the top of the face and all the way round to give your beast a proper body and head. Add on extra zig zags to make it even furrier if you like!
Finally, tell your beast that you love him to magically turn him into a handsome prince. We suggest you leave this part out though - being a beast is so much better!
