Create an engaging poster centered around the theme of an oasis, for a venue named "Oasis Bar" located at La Trobe University. The visual should vividly depict elements synonymous with an oasis - think palm fronds, sand, a DJ booth, and umbrellas, crafting an atmosphere that suggests relaxation and entertainment. At the top or center of the design, prominently display the title "Oasis Bar" with a visual flair that suggests the glow of fluorescent lighting, making it the centerpiece of the poster. Ensure the style is captivating and conveys the essence of a welcoming, vibrant bar setting. Please leave a significant blank space below the title or in another suitable area of the poster. This space is reserved for later addition of specific details such as opening hours, special offers, and age restrictions, ensuring these elements can be customized and clearly presented without cluttering the initial design. The goal is to produce a visually appealing poster that captures the unique spirit of the Oasis Bar, inviting viewers with its promise of a memorable experience. The design should be versatile, allowing for easy incorporation of text details post-creation to tailor the message to various audiences and occasions.
