Nicolas Party's paintings, particularly those focusing on tree trunks, embody a mesmerizing blend of classical inspiration and innovative execution. His work is celebrated for its vibrant colors and stylized forms, bringing a new perspective to traditional subjects. The "Grotto" exhibition at Xavier Hufkens, for instance, showcases Party's versatility across different media, including soft pastel on linen, highlighting his ability to transform familiar landscapes and figures into dreamlike, phantasmagorical scenes. His choice of subjects—ranging from the animate to the inanimate—speaks to a deep engagement with the natural world, filtered through a lens of whimsy and depth​ (Xavier Hufkens)​.

In another exhibition, "Cascade," Party explores natural motifs through a series of new works, including pastels and oil-on-copper paintings. This collection reveals an evolution in Party's artistic practice, with triptychs featuring trees as a central theme. The natural world, in Party's hands, becomes a stage for exploring broader themes of life, destruction, and renewal. His triptychs and cabinet paintings, rendered with meticulous detail, echo the art historical genre's legacy while presenting a fresh, contemplative view on nature's cycles and humanity's place within them​ (Ocula)​.

Party's artwork is a dialogue with the past, yet distinctly contemporary in its execution and thematic exploration. His paintings invite viewers into a reflective, often introspective relationship with the natural world, encouraging a journey into subjective interpretation. Through his unique vision, Party continues to challenge and enchant, merging beauty with devastation to highlight the indivisibility and precariousness of the human and physical worlds​ (Ocula)​.
