These ready-to-use prompts blend the Reddit aesthetic with Gemini’s realistic lighting engine — ideal for both newbies and AI art creators.

1. Ghostface Cinematic Reflection

"A cinematic portrait of a woman standing in front of a mirror in a dimly lit room. Her reflection reveals a Ghostface mask instead of her real face. She wears a simple white tank top and loose jeans. The lighting is cold and moody, with faint fog near the window. The photo has 8K film grain texture, sharp focus on her eyes, and a suspenseful horror-movie feel."

2. Halloween Kitchen Aesthetic (Retro Ghost Touch)

"A hyper-realistic portrait in a Halloween-decorated kitchen, with warm and slightly dark lighting. A woman stands, maintaining her real face and natural hair color, holding an orange retro phone and looking thoughtfully to the side. She wears an oversized black t-shirt with colorful Halloween prints (pumpkins, bats, cats, and ghosts), delicate gold accessories, and light, natural makeup. On the counter, there are two carved pumpkins, scattered seeds, and cutting utensils, suggesting the preparation of decorations. In the background, an old TV plays ‘Friday the 13th,’ showing Jason’s mask in the shadows. The image has a cinematic, nostalgic film tone and 8K photographic realism."

3. Y2K Halloween Girl in Neon Light

"A Y2K-inspired Halloween portrait of a girl standing under pink and purple neon lights, wearing a sparkly silver crop top, butterfly hair clips, and glossy lips. The background shows floating digital pumpkins and holographic bats. The image has a dreamy, vaporwave glow, cinematic lens blur, and 2000s fashion magazine aesthetic."

4. Ghostface in the Streetlight

"A night street scene under a flickering streetlight. A person wearing a Ghostface mask walks alone, holding a candy bucket. Wet pavement reflects orange light. Slight fog drifts through the background. The photo is shot in cinematic style with shallow depth of field and eerie realism."

5. Chucky Makeup Transformation

"A portrait of a woman with half her face painted in a creepy doll-inspired makeup, wearing a striped retro sweater and denim overalls. She smiles slightly, holding a harmless Halloween prop. The lighting is dramatic with red-blue contrast. The background has carved pumpkins and a grainy, spooky cinematic effect."

6. Y2K Party Mirror Selfie

"A retro 2000s-style mirror selfie in a pink bedroom decorated with Halloween lights. The girl wears a mini skirt, platform shoes, and a black crop top with a pumpkin print. She holds her phone with a pink case full of stickers. The lighting is soft with a pastel glow and film camera flash effect."

7. Vintage Ghostly Couple

"A cinematic couple portrait from the 1980s. Both wear formal suits, but faint ghostly masks overlay their faces. The background is an old living room with wood furniture, vintage wallpaper, and dim warm light. The photo has analog film texture, soft grain, and a mysterious nostalgic tone."

8. Glam Witch Editorial

"A magazine-style fashion portrait of a glamorous witch with glossy black lips, pearl eyeliner, and long wavy hair. She wears a silky dark green dress and holds a candle dripping wax. Smoke swirls around her face, with cinematic warm lighting and subtle bokeh background."

9. Ghostface Behind You

"A realistic living room scene where a person sits on the sofa scrolling their phone, unaware that a Ghostface figure stands behind them in the doorway. The lighting is warm and cinematic, inspired by horror movie trailers. The composition focuses on suspense and subtle detail."

10. Pumpkin Y2K Aesthetic

"A stylized digital photo of a girl in Y2K fashion holding a glowing pumpkin. She wears pink sunglasses, metallic eyeshadow, and low-rise jeans. The background features floating stars, holographic ghosts, and pixel glitter effects. Soft neon lighting and dreamy color grading complete the 2000s Halloween vibe."

Reddit Tips for Perfect Results

From Reddit’s top creators, here are some insider tips to get the best Halloween AI edits:

• Use phrases like "ghostface costume" or "man wearing a ghost mask" instead of "Ghostface killer" to avoid content filter blocks.
• Always include "keep my real face" or "do not alter my facial features" for realistic selfies.
• Avoid banned words like "sexy" or "bent over" to keep your prompt SFW.
• Describe your lighting and setting clearly — "dim hallway," "warm lamp glow," "retro pink lighting" all affect the output.
