She designed the award-winning Dragons of Destiny sculpture series, Mistress of the Dragon's Realm dagger series, as well as the Temptation Rides sculpture series produced by The Franklin Mint.

Alleged plagiarism of Bell's work

In 2003, a Flash animation slideshow titled "Family Art Corner" was released anonymous, alleging that a woman named Jan McRae had plagiarized the work of many artists, including Bell, for reproduction in proselytization tracts printed by the Children of God cult. Bell's works, Archangel II, Expedition, Rogue, and Princess Mustang were compared in the slideshow, as were many works by Bell's husband, Boris Vallejo. After the slideshow was released, Karen Zerby, leader of the Children of God acknowledged that McRae had copied the work of others, as did McRae herself, and McRae admitted wrongdoing.
