Vibrant Mardi Gras 3D Graphic Design

"Create a vibrant and colorful 4K flat 3D graphic design featuring a Mardi Gras theme for print-on-demand (POD) shirts. At the center, place a stylized purple and green masquerade mask adorned with gold accents, surrounded by colorful beads. Above the mask, display the text 'HAPPY' in bold, black, uppercase letters with a slight curve. Below the mask, prominently feature 'MARDI GRAS' in a similar bold, black font. The background should be solid white, with no elements touching the edges of the design. Add festive elements such as feathers in green, yellow, and purple, and beads in various colors, but ensure there is ample space around the design, keeping everything centered and balanced. The design should be symmetrical, eye-catching, and suitable for shirt printing, capturing the vibrant and joyful essence of Mardi Gras festivities in a flat 3D style."
