This is a collection of sci-fi and fantasy art from Kilart_.
Kilart_ is a freelance artist from South Korea. Most of it appears to be commissioned work fro various sci-fi and fantasy projects, so it's hard to tell if any of it is just fan art. There are pieces that feature Star Wars and Marvel comic book characters as well. The style is reminiscent of the cover art of Frank Frazetta and other artists that worked on the adult magazine during the 1970's, except done digitally. You can view more art here.
