Mastering Metal: Step-by-Step Armor Illustration Process

Creating realistic illustrations, especially when dealing with complex surfaces like metal, can seem like an intimidating task. However, every great result is just the sum of small, well-executed steps. In this breakdown, I want to share the process behind my latest study piece, "Armor," where I explored building a suit of armor from the initial sketch to the final render.

The secret isn't a magic brush, but understanding structure, light, and how materials react to it. Join me on this visual journey.

Phase 1: The Structure (The Blueprint)

Everything starts with the sketch. At this stage, I'm not worried about details, highlights, or color. My only goal is solidity.

As you can see in the first image, the linework is loose but clearly defines the armor's anatomy. I want to ensure the pose works and proportions are correct before investing time in painting. If the foundation fails, the final result will too

.

Phase 2: Blocking and Values (The Foundation of Light)

Once satisfied with the drawing, I move on to defining volumes. Many artists make the mistake of jumping to color too soon. I prefer working in grayscale (values) first.

Here, I establish the main light source. I define which planes are lit and which are in shadow. It's a "blocking" stage where I separate the main shapes.

Moving forward, I start smoothing transitions and giving more three-dimensionality to the metal plates. The goal is for the armor to already feel "heavy" and solid using only light and shadow.

Phase 3: Definition and Material Rendering

Metal is a fascinating material because it's highly reflective. In this phase, the work focuses on rendering.

I begin defining the edges and cuts of the plates. Polished metal has very sharp value transitions (high contrast), while worn metal is more diffuse.

This is where the piece comes to life. I add imperfections, scratches, and refine secondary reflections. Notice how the contrast between dark and light areas creates that characteristic metallic feel.

Phase 4: Color and Atmosphere

With values well-established, integrating color is much simpler. I use blending modes (like Overlay, Soft Light, or Color) to tint the image without losing the light information I've built.

At this stage, I decided on a warm palette for the armor, contrasting with a more neutral background. Color isn't just decoration; it helps guide the eye and establish the mood of the piece.

Phase 5: Final Polishing (Highlights and FX)

The final touches make the difference between a good sketch and a finished illustration.

In the final step:

1. I add specular highlights (the whitest points where light hits directly) to give that shiny, sharp look.

2. I reinforce ambient occlusion (the deepest shadows in the crevices).

3. I apply a slight global color correction to unify everything.

And there you have it! From a line sketch to a full suit of armor.

Summary for Artists

· Patience: Don't try to finish the illustration in the first hour.

· Order: Sketch -> Values -> Color -> Details.

· References: Always have references of real metals on hand.

I hope this breakdown inspires you to work on your own textures and materials. See you in the next post!
