Cromwell attended the prestigious Gobelins School, where he studied animation. He is the author and co-author of several comics and illustrated books, like Anita Bomba, and adaptations of The Last of the Mohicans and The Sea Wolf.

Published in 2020, Artbook Cromwell Quelque Part ("Somewhere") is Cromwell's first art book. Packed with art, including five stunning 4-page double fold-outs of breathtaking panoramic illustrations.

From the publisher:

All of Cromwell's favourite subjects are tackled in his signature style, with exciting evocative lines and an intense mastery of colour and materials. Our attention is caught immediately with 5 stunning 4-page fold outs, (Yes! 5!), Quelque Part is powerful; laden with evident emotion and tension! Open to any page and be immediately drawn (no pun intended!) into the scene, an observer, yet simultaneously feeling personally involved and entangled in the moment.

Raw images leap from the page without text or comment... we lose ourselves, frozen in the moment, imagining the action about to unfold. These images have a story that we have interrupted, stumbled upon and we anxiously wait for the next moment.
