Please design the exterior of a 15-floor tower for Botanical Museum, with circular and curvature design. The tower should be surrounded by circular columns and ramp which start from ground, each resembling aTree Trunk with tree bumps and displacement. At the end of each column, there should be a garden and a tree. The tower should consist of small parametric units, each with a double height. Focus on creating transformative solutions without being restricted by size. It's important to provide high-quality architectural renderings that showcase the design. The rendering should include the street with cars, depicting a cloudy day in Dubai. Ensure that the entire building and the sky are visible in the design. --s 750
