Ultimate Character Design Guide: Tools & Workflow

Character design is the process of creating personas with specific identities, story backgrounds, and visual traits. A well-designed character does more than just look good—it forms emotional connections with the audience. The process involves two major aspects:

1. Internal Design: Personality, goals, beliefs, backstory, tone, and behavioral traits.
2. External Design: Physical appearance (hairstyle, facial features, expressions), clothing, accessories, posture, and more.

These internal and external elements must work together to create a well-rounded, compelling character. For example, an introverted and calm character may wear minimalist, cool-toned outfits with soft lines, while an energetic and bold one might feature vibrant colors, exaggerated hairstyles, and expressive poses.

1. Define Character Background and Style

Before designing, clarify the character’s universe, function, age group, and psychological motivations. These directly influence appearance and details. For instance, a bard in a fantasy world versus a cyborg soldier in sci-fi will look entirely different.

2. Collect Reference Material

Building a visual database is essential. Use sites like Pinterest , ArtStation , and DeviantArt . Tools like GenApe allow you to explore combinations of visual styles and generate character design drafts quickly.

3. Sketching and Composition

Start sketching by hand or use an AI character generator to create initial concepts. Experiment with various compositions (poses, expressions, dynamics) to explore different directions before refining.

4. Line Art, Coloring, and Finalization

Once you decide on a direction, proceed with clean lines and coloring. Choose a style that fits the character’s role—e.g., oil painting for epic vibes or watercolor for emotional tones. GenApe offers preset style templates to streamline this process.

Try GenApe’s AI character generator, which combines line art and coloring functionalities. You can:

1. Use text prompts to generate black-and-white sketches
2. Upload your preferred sketch to GenApe for stylized coloring

This gives you full control over composition and shape while enjoying the speed of AI generation. Hand-drawn sketches can also be uploaded to apply specific styles, producing polished final designs. Here’s a side-by-side comparison of sketch vs. colored versions created with GenApe:

With an AI character generator, you just need a simple text prompt to instantly create fully composed character illustrations. Let’s explore how to define character styles through AI-generated images with precision.

AI Character Design Prompts

Got a concept in mind but struggling to visualize it? Here are two prompt examples to guide your character design process:

1. Left image: A girl with a yellow hat vacationing under the bright sun (anime style:3)
2. Right image: A Japanese high school girl with long hair, delicate features, and large, bright eyes, wearing a sailor uniform under the sunset (Japanese illustration style:3)

Use parentheses to set style preferences and assign values from 0 to 5—the higher the number, the stronger the style influence.

Setting AI Style Preferences in Character Generation

Using the same prompt but different generation styles can drastically change the outcome. For instance, a “16-bit pixel-style male wizard with a purple cloak and staff” generates nostalgic pixel art with retro colors and blocky shapes. Switching styles changes the visual tone and detail level. GenApe adapts flexibly to your character needs.

Beyond hand-drawing, more creators are using AI character generators for sketching and style experimentation. Here are three popular platforms for AI character design:
