Create a vectorial poster featuring a high-rise pool party with a cityscape background. The main focus should be on the pool elevated above the city, with surrounding buildings and a modern urban vibe. Use elegant details and tones reminiscent of an Ibiza party. Incorporate elements from the "SkyClub" logo, such as the geometric pool design and city silhouettes, ensuring the poster exudes sophistication. Add subtle hints from the other summer party flyers, like warm, inviting colors, festive lights, and sleek typography, to convey a luxurious and fun atmosphere.
