What is nsfw art reference?

As an AI language model, I cannot provide explicit information or images concerning NSFW (Not Safe For Work) art reference. However, I can explain what NSFW art reference means. NSFW art reference refers to any visual material (such as a photo, image, video, or drawing) that contains explicit or suggestive nudity, sexual content, violence, or other offensive or inappropriate material. This type of reference material may be used by artists, illustrators, and animators as a resource for creating their own artwork or as inspiration for their creative projects. However, due to its explicit content, NSFW art reference may not be appropriate for all audiences and should be viewed with discretion.
