Mark Flood's *Sand Castle* is a bold acrylic work on canvas mounted on board, reflecting the artist's characteristically irreverent and layered approach to painting. Flood plays with surface, texture, and cultural imagery to evoke both the transience and constructed nature of ambition, much like the titular sand castle itself. The work exemplifies his ability to oscillate between humor and critique, inviting viewers to question the permanence of the structures — physical and societal — we build.
