A vibrant 80s retro t-shirt design featuring a synthwave chicken sporting sleek, angular sunglasses, confidently standing against a minimalist sunset characterized by bold, geometric lines and vivid gradients. The scene is set with a deep, midnight blue background, with the chicken's feathers reflecting neon shades of cyan and magenta, creating a striking contrast. The chicken's pose is dynamic, as if ready to strut through a futuristic landscape, while palm trees in silhouette subtly frame the composition, adding an extra layer of retro-futuristic flair.
