"Design an avant-garde illustration for '2025' in a sleek graffiti-inspired typography, characterized by a blend of smooth curves and sharp edges. The style should appear refined and professional, retaining graffiti's energy while aligning with a high-quality, industry-standard finish. The text layout is purposefully unbalanced, with each number slightly off-kilter, creating a visually compelling, asymmetric composition that draws the viewer’s eye. The color palette is grayscale with subtle metallic textures, using a gradient that transitions from dark pewter to bright silver, giving each digit a metallic sheen. Background elements include faint digital motifs—like grids, codes, and abstract shapes—that subtly enhance the illustration's futuristic theme. Layer these patterns to add depth, as though they’re layered behind the text, barely visible but adding dimension to the piece. To elevate the futuristic and professional tone, apply holographic effects to parts of the text to give a slight reflective quality, capturing light and producing soft, multi-colored highlights along the edges of the letters. Each number should cast a shadow onto the layered background, creating a three-dimensional effect that amplifies the depth. Subtle gradient transitions within the text add movement and make the numbers appear almost illuminated from within. The overall aesthetic should feel sleek, forward-thinking, and crafted to represent 2025 as a year of both elegance and innovation."
