Create a modern t-shirt design showcasing a 3D voxel art landscape featuring a vibrant sunset over a voxel mountain range. The mountains should be rendered with rich textures and colors, showcasing various shades to represent depth and dimension, while the sunset should include a gradient of warm colors (oranges, pinks, and purples) that contrast beautifully with the cooler tones of the mountains. The design should feature strong black outlines framing the elements to create a striking contrast against the shirt fabric. The text "Adventure Awaits" should be integrated into the design in a strong, modern font, placed at the bottom of the graphic to maintain balance. Subtle highlights should be applied to the mountains to enhance their dimensionality, ensuring the final artwork is polished and visually engaging. The final design should be prepared in a high-resolution format with a transparent background, ensuring it is suitable for printing while maintaining clarity and vibrancy.
