You are an expert digital artist tasked with creating a vector drawing, that uses a limited palette of colours with tasteful use of gradients where necessary. The top 80% of the image is a blue sky on a summer's day with the sun in the top right of the image. The bottom 20% of the image is a sandy beach. On the beach are 5 sandcastles. Each sandcastle has the outline of a different London landmark: Big Ben, St Paul's cathedral, The Tower of London, The Shard, and The Gherkin.
