One of my favorites to play with was the Liquify tool. You can experiment with tools like blurring (which can provide some cool depth illusions), opacity and noise (which can give your work a less grainy look).

If you tap that, you'll see (surprise!) more editing tools. Next to the wrench icon is a little magic wand icon. The liquify edit options in the Adjustments tab. You can choose to control the blur intensity on the entire layer (slide your pencil back and forth on the screen to increase or decrease the blur) or take a more detailed approach by choosing Pencil (like a more focused approach, similar to the smudge tool). Once you have the drawing you want to blur, tap the icon that looks like a magic wand in the upper left and choose Gaussian Blur. The brush size and opacity are adjustable on the left-hand side. When you tap the smudge tool, you can select from a number of different brushes to keep consistency with the brush you originally painted with. The smudge tool lives between the paintbrush and eraser icons in the top right (it looks like a finger pointing diagonally). If you're not quite comfortable with the more advanced blend modes, the smudge tool and Gaussian Blur have saved me many a headache. Zooming in on pixels and trying to grab colors to make something look smoother is time-consuming and exhausting. Using blend mode on layer 7's clipping mask. I'd have had better luck controlling the color if I used Quickshape, but you can also continue to hold down and drag left or right to adjust the ColorDrop threshold. Sometimes if you use ColorDrop, you might notice that it 'spills' on the whole canvas. The color will either fill your whole canvas, or work around the shapes you've already placed. Drag the color to where you want it on the canvas and let go. To use ColorDrop, choose the color you want from your palette, and tap and hold on the color circle in the upper right corner.

The Procreate ColorDrop feature acts like the bucket fill once did on Microsoft Paint. This tool is also helpful when you're trying to achieve a smoother blend. With the eyedropper tool (which is also customizable in gesture controls) you can hold down over a color to pick it up, or hold down, drag and zoom to get more detail in your use of color.

One of my favorite parts of Procreate is how much you can customize the colors you use, and in such detail. You can also use New from File or New from Photos to use a premade palette from another artist or generate a palette from a reference photo. New from Camera opens your iPad's camera and lets you capture a color palette by snapping a photo. When you tap the '+' you can also choose New from Camera, New from File or New from Photos. If you go back to the palettes tab, you can name it or delete a palette if you don't need it anymore. If you change your mind, tap and hold on a color to delete it from your palette. To add colors to the palette, just select the color you want and tap in the palette box to keep it. This will create a new empty palette that will be available when you go back to the color panel. To manually build a color palette, tap the '+' in the top right next to Palettes. Procreate has three premade palettes that you can set as default, or you can also add your own color palette a few different ways. A look at the color disc and colors added to a new palette.
