Create a dynamic urban graffiti-style vector illustration titled "Urban Freedom," featuring a bold abstract bird in flight that symbolizes freedom. The bird should have wings shaped like splashes of vibrant colors—green, red, and yellow—integrated with graffiti-style streaks and splatters to convey a sense of motion. Surrounding the bird, include graffiti motifs such as musical notes, stars, and dynamic shapes, all in complementary colors that enhance the overall vibrancy. The background should be clean and transparent, allowing the bold outlines and colors to pop. The composition should exude energy and pride, blending graffiti culture with Bangladeshi symbolism, while ensuring that the bird remains the focal point of the illustration. Consider adding texture overlays and gradients to enhance depth and visual interest.
