Prompt:

Create a digital illustration of a person lying on their side on a sandy beach, with a light-colored towel beneath them. The person should have a short, straight bob haircut with bangs and is wearing a blue bikini. They are resting their head on one hand, with their legs slightly bent and their other hand resting on their thigh. The scene should be set during the day with natural lighting, and the background should feature the sandy beach extending into the distance. Ensure the overall mood of the illustration is relaxed and serene.
