Epic High Fantasy Twin Moons
A lone armoured rider on a chestnut warhorse cresting a windswept moorland ridge, modestly covered in a long travel cloak with chainmail glinting at the throat, a banner pole strapped to the saddle and a wolfhound pacing at the horse hooves. Far below, a vast valley of pine forest opens out toward a distant walled city built into the cliffs, twin moons rising on the horizon.
Cool blue dusk light raking across the heather, warm torchlight from the distant city as a single golden accent, soft mist clinging to the lower valley. Painterly oil-style brushwork with thick visible strokes, palette of slate blue, mossy green, burnished gold and cream stone, sweeping epic cinematic mood that reads as printed cover art and not a render.
Leave the entire upper sky open for a tall foiled serif title that reads "THE LAST WARDEN" stacked in two centered lines, and reserve a calmer band of moorland along the bottom for the author "Halden Reeve" in a smaller refined serif. Keep both type areas free of cluttered detail.
