Welcome @oneward! Procreate has tons of great brushes that come with the software, so start with getting comfortable with the default set of tools while you check out what others are using. The best way to start getting comfortable with digital painting is using the generic painting round brush. This can feel clunky and limiting at first, but it's one of the most versatile tools in the set and you'll be amazed at what people can create just by varying the size or opacity. Once you're comfortable with how the default tools work, start to dig into the preferences of each brush, and learn how to make adjustments to achieve what you're looking for. A few favorites that come with Procreate are the Procreate Pencil for sketching, and the Syrup Brush for inking. If you're looking for other brushes not included in Procreate, I highly recommend both of Lane Brown's Procreate Master Packs available in the tools section, they're some of the best out there! Good luck, can't wait to see what you're working on!
