Vampire lips and fangs pattern which I created for Halloween some time ago. It is a vector illustration drawn in Affinity Designer, made as a seamless pattern. Hot pink lipstick, some sharp teeth over very dark purple background. Great designs for a gothic style or just for some holiday mood. Later added art prints and products to my Redbubble and Society6 stores.

Lastly, while on the topic of sharp teeth, see also this fun evil monster here.
