Lesson 3 of 13 · Module 1: Image Generation Craft
Character and Style Consistency Across a Set
Generate a set of 4 images of the same character or in the same visual style that read as belonging to one series.
Pick A: “This ONE Prompt Creates Flawless Consistent Characters Sheets
Uses Nano Banana 2 to build a multi-angle character reference sheet, essentially the contact-sheet consistency check the lesson asks for. Good tool alignment, just longer than ideal; timestamp to the sheet-generation segment if trimming for class use.
Pick B: “Character Consistency Using Image References | Magnific Academy
Very short, dense, demonstrates reference-image anchoring (the exact method named in the lesson) directly on screen. Tool is Magnific, not Gemini, so flag as a rival-tool demonstration of the same workflow.
Objective
Why This Matters
A single striking image is easy now, almost anyone can get one. A believable set, the same character or the same look across a thumbnail, a carousel, or a sequence of video shots, is the actual job and it’s much harder. This is the difference between a demo reel of unrelated cool generations and something that reads as a produced series. It’s also the exact skill that makes the video sequencing in Module 2 possible, so treat this lesson as load-bearing, not optional polish.
The Technique
Consistency fails almost every time for the same reason: you re-describe the character from memory in each new prompt, and memory drifts. The fix is to stop describing from memory and start anchoring.
Two durable methods, use either or both:
- Reference image anchoring. Generate or choose one canonical image of the character or style. Feed that image into every subsequent generation as a reference input, and write the new prompt only for what’s different (the pose, the scene, the angle), not the character itself. The reference does the identity work so your words don’t have to. - Locked description block. Write one fixed paragraph describing the character or style in specific, reusable terms (face structure, hair, costume, palette, rendering style) once. Paste that exact block, unchanged, into every prompt in the set. Only the scene-specific portion of the prompt changes between generations.
Whatever specific feature your tool calls this (seed locking, style reference, character reference, image conditioning), the underlying method is the same: anchor once, carry forward, never re-improvise the description. That’s the part that survives a tool swap. The button name won’t.
Watch For This
Good
- Face structure, costume, and color palette hold steady across all 4 images.
- Rendering style (photographic, illustrated, 3D) is identical across the set.
- A viewer with no context immediately reads the 4 as one series.
Classic Failure
- The character subtly changes generation to generation, different actor playing the same role each time, because the description was rewritten from memory instead of reused verbatim.
- Style drifts (one image reads as a photo, the next as an illustration) because the style clause wasn’t part of the locked block.
- The set only looks consistent to you because you already know it’s supposed to be the same character; a cold viewer sees 4 different people.
Your Drill
Build a 4-image set of one character or one fixed visual style, in 4 different scenes, poses, or angles, using either reference-image anchoring or a locked description block carried unchanged across all 4 prompts. Submit the 4 images as a contact sheet plus the reused reference image or description block.

Pass Checklist
Lesson complete
Criterion met: Viewed cold, side by side, all 4 images show the same face structure, costume/color palette, and rendering style with no visible drift between any two, confirmed either by an outside reaction or your own review after at least a few hours away from the work.

Noted.
Coach Note
The tell that you’re drifting is subtle at first, a slightly different nose, a slightly different jacket color, and it’s easy to wave off individually. Line all 4 up in a grid before you submit. Drift that’s invisible one image at a time becomes obvious the second you see all 4 at once.
