How do I improve the quality of Dalle 3 image output

I’m attempting to create a graphic novel using this. I can’t seem to get the picture to get clearer that it already is, in the sense that the image appears to have unclear elements. Is there a way to clean this up?

Here is the prompt

A 1970s scene in set in Africa. Panoramic View, a beach, with a harbor, many fishermen boats, two dhows, busy market, bus stop with old buses and vans to the right, ocean to the left. Sunny hot day, seagulls in the air. Rendered in a deep natural colour animation style, with colourful elements. It is gritty, hyper-detailed, 8k resolution concept art, it uses the ligne claire style, inspired by Ukiyo-e and Anime Key Visual, with natural lighting and a beautiful composition. Format Portrait
