[3] In 2017, Heimans produced a portrait of The Duke of Edinburgh to mark his retirement from public duties and highlight his family history and Danish roots.

The work, set in Dumfries House in Scotland, focuses on the Prince's commitment to environmental protection and sustainability, architectural preservation and the notions of harmony between the natural world and the built environment.

[7][non-primary source needed] Heimans was commissioned by Frederiksborg Castle to paint Frederik, Crown Prince of Denmark, who unveiled his portrait in May 2018 to mark his 50th birthday.

His Shakespeare400 series of celebrated authors, including Margaret Atwood, Howard Jacobson, Anne Tyler, Gillian Flynn, Tracy Chevalier and Jo Nesbo was exhibited at Globe Theatre in 2016.

[9] In May 2018, a major retrospective at Frederiksborg Castle, the Museum of National History, opened by Queen Margrethe II of Denmark, saw many of Heimans‘ most celebrated portraits displayed.

[10] The Director of the Museum, Mette Skougaard said the exhibition gave viewers "a rare opportunity to appreciate the range and depth of one of today's leading portrait artists".

[11] "Heimans's luminous work is built on a foundation of traditional techniques through a mastery of complex composition his subjects are woven into their surroundings to create a multi-layered narrative environment…building a landscape of the soul".

Margaret Atwood, Anne Tyler, Tracy Chevalier, Gillian Flynn, Jo Nesbo and Howard Jacobson sat for him, and the paintings were exhibited at the Globe.
