"Design a heraldic shield for a prestigious brow military academy. The shield should prominently feature the ancient letters 'D' and 'M', presented in an elegant and sophisticated style, adding military renaissance ornaments. Use a color palette that combines bright gold and lustrous black, with a design that conveys luxury, modernity, and power. The shield should be hung on a rustic wall of ancient weathered bricks, with opulent, heavy drapes in complementary hues framing the scene, highlighting the contrast between the rusticity and futuristic elegance of the shield."
