This course is about getting the images out of your head and onto the canvas. SEOK98 walks you through his entire process, from the first vague idea to a polished, semi-realistic illustration. Itβs not about copying a reference; itβs about building a personal workflow for composition, color, and texture that lets you tell your own stories.

- Integrate characters and backgrounds into a unified scene.
β Requirements

π Description
This isn’t a “paint-by-numbers” tutorial. SEOK98 focuses on the thinking behind the brushstrokes. The core of the course is learning to visualize ideas intuitively. You’ll start by building mood boards and doing rough sketches, then move into the nitty-gritty of composition, color, and texture.
The curriculum is built around practical exercises. You’ll practice color croquis to break down the barrier between drawing and painting. You’ll learn how camera principles like white balance and exposure can inform your digital rendering. The goal is to give you a repeatable process for creating illustrations that have a strong sense of mood and narrative, not just a pretty picture.
SEOK98βs style is distinct: matte, rough, and deeply atmospheric. He breaks down how he achieves that look, from his specific brush settings to his method of texture rendering. The course also dedicates significant time to backgrounds, treating them as a character in the scene rather than an afterthought.
π§βπ Who this course is for
- Illustrators who can draw but struggle to come up with original compositions and ideas.
- Artists who want to develop a more intuitive and less rigid workflow.
- Anyone looking to add a strong narrative and mood to their semi-realistic character art.
