My first recommendation is "Finding Your Art Style with Textures in Procreate" by Claire Makes Things. This class is a must for anyone seeking to explore their personal style and learn how to bring their artwork to life through textures.
Claire's teaching style is incredibly clear. She encourages you to break out of your comfort zone, which can be a bit scary- but she makes it really fun!
Not only was I inspired by her mid-century style illustrations, but getting to see her creative process was a real treat. It's no surprise that this class was selected as a Staff Pick by Skillshare!
