Create a vibrant and eye-catching marketing poster background that features a gradient blend of blues and greens. Incorporate abstract shapes and dynamic lines that give a sense of movement and energy. Add subtle textures, such as watercolor splashes or light bokeh effects, to add depth. The overall composition should be lively and modern, with ample negative space for text overlays while maintaining a professional and engaging appearance.
