Design a bold and vibrant graphic for a t-shirt featuring a fierce lion with a flowing mane, incorporating tribal patterns and geometric shapes around the edges. The lion should be in mid-roar, symbolizing strength and power. Use a mix of warm colors like deep reds, oranges, and yellows, along with contrasting cool tones like blues and blacks to create a dynamic, eye-catching composition. The design should feel modern yet timeless, appealing to a wide audience with an adventurous spirit.
