Step 1
So let's get started. First, we make a sketch of the main parts of the body: the head, the body, and also the shield. But so far in the form of ovals and straight lines.
Step 2
Now draw a raincoat, a leg shield.
Step 3
Now draw more details, remove original outlines in the form of straight lines and ovals with an eraser where they are not needed.
Step 4
In the next two stages we detail the details: face, drawing on the shield, we pay more attention to clothes and armor.
Step 5
So we came to the final stage. Now apply the shadows where they need to look at the figure below. Your knight should look like something like this.
