Now I’ll paint the character. I’m going to use the “Airbrush” and “Color Mixer” brushes that I introduced in part 2.
Like with the background, I merge the line art and base color layers before I start painting.
 Painting the character’s head
After merging the layers, I felt that there was little variation in color on the character, so I add a new layer and softly paint in a blue-green color around the face and hat with the “Airbrush".
Using too many bright blending modes can make the gradation in bright areas appear white and create an oversaturated effect, so I leave the blending mode as [Normal]. I only added this color to adjust the tonal balance, so I lower the opacity to 58%.
Some people find it hard to paint if the line art sits on top of the base colors, but I think it is very easy to paint using the lines. I make the lines thinner where the light hits, paint color on top to make the lines fainter, and use the lines to add shadows close to the boundary lines.
I ignore the line art when painting the tips of the hair to create a silky soft effect.
I very slightly adjust the position of the right eye.
 Painting the character’s clothes
Again, I start by painting the shadows and then adjust the shape using highlights.
I used the “Color Mixer” brush on the green clothes around the waist to make the fabric look stiff.
I felt that the leg was slightly too long, so I select it with the Lasso tool and then move it with the [Free Transform] tool. Then I paint so that the adjusted part isn’t visible.
 Painting metallic parts
You can easily create a metallic effect by painting with clear contrast.
After painting the shadows and adjusting the shape with highlights, I create a new layer set to [Add (Glow)] to add reflecting light.
 Adjusting the colors
Compared to the beginning, the colors have become a little duller after painting the top layers, so I add another layer set to [Overlay] and paint in shades closer to the base colors.
(Left: When the layer is set to [Normal]; Right: After clipping to lower layers and changing to [Overlay] mode)
Then, I add reflective highlights to make the edges clearer.
I’ve now finished painting the character.
