With the Central Phrase "Explore the Wilderness Within" Prominently

Design a poster with the central phrase "Explore the Wilderness Within" prominently featured. Surround the text with detailed, nature-inspired visuals such as textured depictions of mountains, meandering rivers, and dense forests. Show two distinct versions of the poster: one displayed on the wall of a cozy, wood-paneled cabin and the other fastened inside the rugged interior of an explorer’s backpack, with subtle lighting accents that emphasize the intricate artwork.
