Your first Procreate illustration: draw a leaf with built-in brushes
Make one leaf with 6B Pencil and Monoline. Follow a concrete layer sequence from rough sketch to filled shape, clipped shadow, editable backup and PNG.
Make one small illustration, learn the tools it needs, then choose your next skill. Start here if a blank canvas feels harder than the drawing itself.

I recommend a leaf or another simple shape for a first session. Draw its silhouette in one color, then add a few details in a second color. Use that small project to learn a brush and a simple layer stack before saving the result. The useful outcome is understanding those decisions.
Follow the first Procreate illustration guide for that complete drawing route. Return here when you want to choose what to learn after it.
If you prefer a video-led introduction, Procreate's official four-part beginner series moves from fundamentals through painting and editing to actions and animation. You can leave animation until a project needs it.
For a backup, keep a separate editable copy in a cloud or external storage destination you can access. Procreate's artwork backup guidance explains manual export from the Gallery. A second file on the same iPad does not protect against losing that device; confirm that your chosen destination has received the file.
Choose a complete project when you need a starting point. Use the focused lessons when you already know what you want to change.
Start with a complete small project, then use the focused drawing and reference guides when the task calls for them.
Then pick the skill that would improve this drawing. A more controlled line, a cleaner fill or a better-organized layer stack is a useful next lesson; completing the entire library is not a prerequisite for making another picture.
