Fantasy art is a genre of art that depicts magical or other supernatural themes, ideas, creatures or settings. While there is some overlap with science fiction, horror and other speculative fiction art, there are unique elements not generally found in other forms of speculative fiction art. Depictions of ancient myths and legends, as well as depictions of modern day fantasy in the form of divine interventions and other magical or supernatural forces, are very common elements, and help distinguish fantasy art from other forms. Dragons, wizards, fairies and other fantastical and mythical creatures are common features in fantasy art.
Fantasy art is strongly linked to fantasy fiction. Indeed fantasy art pieces are often intended to represent specific characters or scenes from works of fantasy literature. Such works created by amateur artists may be called fanart.
Concept art is a form of illustration where the main goal is to convey a visual representation of a design, idea, and/or mood for use in films, video games, animation, or comic books before it is put into the final product. Concept art is also referred to as visual development and/or concept design. This term can also be applied to retail design, set design, fashion design and architectural design.
