As a prompt generator for a generative AI called "Midjourney", you will create image prompts for the AI to visualize. I will give you a concept, and you will provide a detailed prompt for Midjourney AI to generate an image.
                            
                            Please adhere to the structure and formatting below, and follow these guidelines:
                            
                            Do not use the words "description" or ":" in any form.
                            Do not place a comma between [ar] and [v].
                            Write each prompt in one line without using return.
                            Structure:
                            [1] = Create a promotional image for a motorcycle race day opening. The image dimensions should be 1920 pixels in width and 420 pixels in height. Please use a color palette primarily consisting of black, white, and red.  Design Concept: Design a scene with a prominent racetrack in the center. The racetrack should be wide, covered in a dark black asphalt texture. The track extends into the background, creating a sense of depth and perspective. In the center of the track, place a vibrant red motorcycle. The motorcycle should catch the light, creating highlights on its surface.  Position a rider on the motorcycle, dressed in a sleek white racing suit. The rider's posture should convey a sense of motion, leaning forward slightly. The rider's helmet can feature reflective elements that mirror the surrounding racetrack. Add subtle white streaks behind the motorcycle and rider to further accentuate the sense of speed.  Surround the racetrack with dark shadows and smoke, hinting at the anticipation and intensity of the race. The smoke should have subtle hints of red, blending with the motorcycle's color.  Use bold black typography to display the words "Motorcycle Race Day" at the top of the image. The font should be modern and dynamic, with elements of flames incorporated into the design. The flames can transition from red to orange, creating an exciting visual effect.  Directly beneath "Motorcycle Race Day," use clean white lettering to write "Opening Event." This text should be straightforward and easily readable against the dark background.  The background of the image should feature a gradual gradient from deep black at the top to rich red at the bottom. This gradient adds a sense of atmosphere and energy to the design.  Remember to adhere to the specified dimensions of 1920px by 420px.  Feel free to use graphic design software to create the image based on these instructions.
                            [2] = a detailed description of [1] with specific imagery details.
                            [3] = a detailed description of the scene's environment.
                            [4] = a detailed description of the compositions.
                            [5] = a detailed description of the scene's mood, feelings, and atmosphere.
                            [6] = A style (e.g. photography, painting, illustration, sculpture, artwork, paperwork, 3D, etc.) for [1].
                            [7] =  a detailed description of the scene's mood, feelings, and atmosphere.
                            [ar] = Use "--ar 16:9" for horizontal images, "--ar 9:16" for vertical images, or "--ar 1:1" for square images.
                            [v] = Use "--niji" for Japanese art style, or "--v 5" for other styles.
                            
                            
                            Formatting:
                            Follow this prompt structure: "/imagine prompt: [1], [2], [3], [4], [5], [6], [7], [ar] [v]".
                            
                            Your task: Create 4 distinct prompts for each concept [1], varying in details description, environment,compositions,atmosphere, and realization.
                            
                            Write your prompts in english.
                            Do not describe unreal concepts as "real" or "photographic".
                            Include one realistic photographic style prompt with lens type and size.
                            Separate different prompts with two new lines.
