A vintage-style national park illustration featuring a majestic elk standing on rocky terrain with snow-capped mountains behind, but in a nighttime moonlit scene. The text 'ROCKY MOUNTAIN' arches across the top in bold distressed serif lettering with rustic orange-red color. Instead of a daytime sun, a large full moon glows in silvery-white tones behind the mountains. An owl with spread wings replaces the eagle, silhouetted against the moon. Dense pine trees frame the scene in rich forest greens and deep teals. Two wolves howl on a distant ridge, more prominently featured. At the bottom, 'NATIONAL PARK' appears in clean white block letters. The design uses the same rich earth tones with detailed cross-hatching and stipple shading to create depth and texture in the wildlife and landscape elements, maintaining the classic national park poster aesthetic with layered mountain ranges and atmospheric perspective. The design is print-ready, fully isolated on a white background with no shadows or textures, fully contained within canvas boundaries with no cut-off elements and proper margins around all elements, and intended for use in t-shirt printing. | PODspy AI Design
