10 AI Thumbnail Prompts You Can Copy and Customize

1. Obby Thumbnail: The Almost-Impossible Jump

Customize: Avatar, obstacles, hazard, and colors.

Create a 16:9 thumbnail for my Roblox obby, featuring [AVATAR: a blocky avatar wearing a yellow hoodie and black headphones] attempting [CHALLENGE: a jump between two narrow floating platforms] above [HAZARD: a glowing lava pit].

If I attach a reference, preserve the avatar’s outfit and the obstacle course’s actual design. Place the avatar in the right half, frozen mid-jump with arms spread and a startled expression. Use a low camera angle so the gap feels dramatic while both landing platforms remain visible.

Show only three or four obstacles in the distance to communicate the course without clutter. Use [COLORS: orange lava, purple platforms, and cyan sky], with bright edge lighting around the avatar. Keep the blocky character proportions and crisp 3D game appearance.

Leave a clean dark area in the upper-left for text I will add later. Keep the face, feet, and landing platform sharp. Avoid extra limbs, floating accessories, tiny UI elements, logos, watermarks, and generated text.

2. Tycoon Thumbnail: Starter Base vs. Dream Factory

Customize: Tycoon theme, buildings, avatar, and colors.

Use only upgrades that exist in my game. If reference screenshots are attached, retain their building shapes, materials, and equipment. Place [AVATAR: a blocky builder wearing blue overalls] near the center, looking excited and pointing toward the advanced factory.

Make the starter side muted and simple; make the advanced side bright with [COLORS: electric blue and gold]. Use matching camera angles so the progression is easy to understand. Add one broad arrow between the buildings, without covering the avatar or key machines.

Leave a quiet band across the top for my headline. Use crisp 3D rendering and recognizable blocky geometry. Avoid cash amounts, fake rewards, unreadable labels, crowded machines, logos, watermarks, and generated text.

Leave open space across the top for my headline. Create tension through distance, shadow, and expression. Use blocky 3D styling. Avoid gore, excessive darkness, additional monsters, distorted hands, logos, watermarks, and generated text.

Use flat cool lighting on the starting side and warm golden lighting on the finished side. Keep the split clean, without extra borders or decorative clutter. Leave a quiet top band for my headline.
