Operation Neptune: The Untold Story of June 6, 1944, on Omaha Beach

Design me a premium, bestselling-quality historical war book cover in portrait orientation, 6 inches by 9 inches, front cover only. This is what I want: a dramatic, cinematic World War II D-Day scene that stops someone scrolling through Amazon search results and makes them stop and look. The main visual: a wide, low-angle view of Omaha Beach at dawn, June 1944. Show silhouettes of American soldiers wading through shallow surf toward a smoke-covered shoreline, backlit by a pale orange and grey sunrise breaking through thick cloud cover. In the background, steep bluffs rise up with faint outlines of fortified bunkers and barbed wire obstacles jutting from the sand in the foreground, partially submerged in water. Landing craft are visible in the distance on a churning grey-blue sea. The mood must feel tense, solemn, and heroic all at once, not glorified or cartoonish, but weighty and respectful, the way a serious historical documentary poster would feel. Color palette: muted, desaturated tones dominated by steel grey, deep navy blue, charcoal black, and burnt orange or amber for the sunrise light breaking through the smoke. Avoid bright, saturated, or cheerful colors entirely. This needs to feel authentic to 1940s wartime photography, almost like a colorized archival photograph with cinematic grading applied. Typography and placement, please follow this exactly: At the top third of the cover, in large, bold, all capital letters, place the title OPERATION NEPTUNE. I want this to be the single biggest, boldest text element on the entire cover, easily readable even as a small thumbnail on Amazon. Use a strong, condensed military stencil or serif typeface, white or light sand color, with a subtle drop shadow so it stands out clearly against the sky and smoke behind it. Directly beneath the title, in noticeably smaller but still clearly legible text, place the subtitle THE UNTOLD STORY OF JUNE 6, 1944, ON OMAHA BEACH. Use a clean, slightly narrower serif or sans-serif font, in a lighter grey or muted gold tone, centered directly under the main title. At the very bottom of the cover, centered, place the author name DAVID A. GRINER in a smaller, elegant serif font, gold or off-white, clearly separated from the main title so there is no visual confusion between title and author. Please double check the spelling exactly as I've written it: OPERATION NEPTUNE, THE UNTOLD STORY OF JUNE 6, 1944, ON OMAHA BEACH, and DAVID A. GRINER. No misspellings, no dropped letters, no extra punctuation. I want the overall composition to feel premium and genre-appropriate, comparable to top-selling traditionally published World War II history books, immediately signaling serious, high-quality narrative nonfiction rather than a generic stock photo cover. The title needs to dominate the thumbnail so it's instantly readable even at a small size in search results. This is going to be the face of my book, so please make it count.
