Creating 30 Character Portraits with Consistent Style

When the Aztec Samurai Adventures series needed character portraits for 30 distinct characters, the challenge wasn't generating individual images — it was making all 30 look like they existed in the same world.

The Consistency Problem

AI image generation is inherently variable. The same prompt can produce wildly different results across generations. For a character gallery, this is a fundamental problem:

• Characters must have distinct features but shared artistic style
• Lighting, color grading, and composition must feel unified
• The "world" they inhabit must be visually coherent

The Solution: Style Anchoring

The approach uses three layers of consistency:

Layer 1: The Master Style Header A detailed prompt prefix that defines the artistic DNA — rendering style, lighting setup, background treatment, and color palette. Every character portrait starts with this same header.

Layer 2: Character-Specific Parameters Each character gets a defined set of physical attributes, clothing, and distinguishing features. These are documented in a character sheet and referenced consistently across every generation.

Layer 3: Post-Processing Pipeline After generation, every portrait goes through the same post-processing workflow — color grading, contrast adjustment, and cropping to a standard format. This final pass smooths out any remaining inconsistencies.

The Result

30 character portraits that feel like they were illustrated by the same artist for the same project. Each character is immediately recognizable and distinct, but the visual language ties them all together.

This character consistency system is the same one we apply to children's book illustrations — where maintaining the same character appearance across 32 pages is critical.
