​
Use multiple fills and gradients

Image Instead of relying on a single fill layer to add color to your shape, try using multiple fills. By using a mix of solid and gradient fills, you can create a textured effect. Keep in mind that you’ll need to adjust the gradient stoppers’ alpha so that all of your layers are visible.

​
Use gradients on strokes

Image Much like fill layers, you can add gradients to your strokes. While this won’t fit with every style, it is a good way to create rim lighting.

​
Use caps and joins

Image Instead of leaving the corners and ends of your stroke at the default setting, try using the various cap and join options.
