Tanner’s signature style is known for the meticulously detailed tangles of branches and elegantly draped Spanish moss in silhouette against ethereal, jewel-toned landscapes. His expert use of color captures the glow of light filtered through mist and fog. His work reflects a fascination with atmospheric light and the effect it has on color and form.  The interplay of color and contrast brings a strong feeling of depth and allows each image to change dynamically as natural light changes throughout the day.

"The Departure Series" is a captivating collection that marks a significant evolution from the artist's signature silhouetted trees. With a bold foray into abstraction, this series weaves a tapestry of organic shapes and gentle hues, creating a narrative that is both individual and interconnected. Each piece serves as a chapter in a larger story, exploring themes of home, movement, nature, and contemplation. The series employs a softer palette, eschewing stark contrasts for a blend of overlapping forms that invite the viewer to look deeper and find hidden details within—a bird, a branch, a whisper of the wind. The result is a cohesive exploration of tranquility, subtlety, and the spaces between the known and the imagined, offering a reflective journey through color and form.

The "Nocturnus Series" stands as a captivating exploration of darkness and subtlety, embodying a quiet intensity through the interplay of shades, tints, and sheens of black on black paint. Each piece invites the viewer into a nocturnal world where the nuanced textures of darkness are the forefront of visual experience. With selective use of mica or metallic paint, splashes of color occasionally break the monochrome to highlight elements of the natural world, like the moon's gentle glow or the silent presence of a crow. This collection, although varied in its depiction of nighttime motifs, maintains a thematic unity, emphasizing the allure and depth of darkness and its profound ability to draw out contemplative tranquility.

This series represents Tanner's profound journey into the abstract realm, marking a significant pivot from his signature silhouetted trees. Each piece within the collection stands as a testament to the raw and uncharted territories of artistic expression. The series delves into the essence of emotion and the metaphysical, employing a bold palette and dynamic forms to explore the relationship between nature and the intangible. Through these works, Tanner challenges the observer to find order in chaos, meaning in the undefined, and personal resonance within the universal.

The Designer Series by Tanner is a compelling foray into the realm of abstraction, where the focus is on the intrinsic elements of design—form, color, and texture—rather than the depiction of tangible scenes. This series represents a creative playground where conventional boundaries are blurred, and each canvas becomes an exploration of aesthetic principles. Tanner employs a more liberated brushstroke, a vibrant and often unexpected color palette, and a rich interplay of textures that challenge the viewer's perception. The result is a collection of paintings that invite introspection and curiosity, urging the audience to interpret the visual language on their own terms. The abstract nature of these pieces allows for a personal dialogue between the artwork and its beholder, making each encounter with the Designer Series a unique and intimate experience.

The "Halloween Miniatures" series is a captivating collection of thirteen 4x4" canvases, each one a portal to the quaint and curious side of Halloween. Tanner's use of silhouetted figures such as a watchful crow, an upside-down bat, and a stealthy cat against backgrounds of traditional Halloween orange, eerie greens, and midnight blues captures the essence of the season. The inclusion of a haunted house, with its windows aglow with mysterious light, and a spider poised on its delicate web, adds to the storytelling charm of the series. A small mouse, perhaps the most unassuming of Halloween creatures, makes a cameo, reminding us that size is no measure of impact in art. Each piece, framed boldly, stands as a testament to the holiday's iconic imagery, inviting smiles and a touch of the nocturnal wonder that defines Halloween.
