Lineart

There are SO many ways you could do line art.

The first way is just black lines! Regular, plain black lines.

The second way is blending them in. This is usually used for realism.

The third way it coloring the lines to mach the color inside. For example, if you drew a blue shirt, you would color those lines blue.

The fourth way is just simply doing the lines, coloring the picture, then erasing them.

The fifth way is using different tools. For example the crayon tool, the airbrush tool, or the brush tool.

These are ways I personally do my line art. I haven't really seen or heard of any other ways, but i bet there is a lot!
