First, I will introduce tools and functions needed to create illustrations.
To create a new canvas, click [File] menu → [New] and specify the canvas size and resolution.
Set the [Basic Expression Color] to "Color" when drawing illustrations.
I'm going to select a tool, and draw on the canvas.
Select a tool you want to use from the [Tool] palette on the left.
Use the [Color wheel] to change colors.
Select a color with the circle, and select saturation and brightness from the square.
I'll choose the [Pencil] tool from the [Sub tool] palette.
Different types of pencils are stored here.
They each have different drawing styles and textures, so choose one that you like.
When choosing a tool from the [Tool] palette,
several other tabs will appear in the side [Sub tool] palette.
For example, when you choose the [Pencil] tool, [Pastels] will be in the [Pencil] sub tool group.
The [Pastel] sub tool contains tools with different nuance than pencils,
so you can use them according to your preference.
Similarly, you can select the [Marker] sub tool when selecting the [Pen] tool,
or [Watercolor], [Oil paint] and [India ink] when selecting [Brush] tools.
Other than the pencil, there are many other drawing tools, such as:
the [Pen], the [Eraser], the [Airbrush], the [Brush] tool (which copies traditional materials), and color blending tools.
In the [Tool property] palette, settings of the current tool like brush size and stabilization can be customized.
Additional tools can be downloaded and imported from "CLIP STUDIO ASSETS" .
Try looking for materials; you might just find something you like.
In the bottom right is the [Layer] palette.
The layers you draw on are all stored here.
Drawing lines on different layers makes it easier to edit parts and change colors.
Zoom in and out to draw at a comfortable scale with the [Navigator] palette.
If you need to correct something, redraw with [Redo] and [Undo] functions.
Were you able to operate pen tablet?
Once the set up is done, you can get right into drawing.
There are more videos where I introduce the drawing process for illustrations and manga, that you might find useful,
when learning about different the functions. Make sure to check them out.
