Joanne Greenbaum's *Workbook* is an energetic oil on canvas that pulses with spontaneous, gestural mark-making, layering bold lines, organic shapes, and playful scrawls across the picture plane. The composition feels simultaneously chaotic and deliberate, evoking the visual language of personal notation, doodling, and stream-of-consciousness drawing. Greenbaum's irreverent use of color and form transforms the canvas into a kind of visual diary, blurring the boundaries between fine art and the intimate, exploratory nature of a sketchbook.
