A vintage-inspired flat 2D vector illustration featuring a luxurious infinity pool overlooking the ocean, surrounded by tropical plants and a sun lounger resting beside the water. In the background, the horizon stretches beneath a setting sun, casting a dreamy glow. The design has a hand-drawn sketch style with fine lines, subtle shading, and a slightly distressed texture for a nostalgic feel. Bold arched text at the top reads 'Honeymoon Bliss' in an elegant serif font, with a delicate phrase below that says 'Relax & Unwind.' The entire design is monochromatic in a soft pastel blue, isolated on a clean white background for a serene and stylish aesthetic.
