The great thing about working in acrylic is that it's fantastic for beginners. As soon as you gather your supplies and watch a basic tutorial video, you can quickly gain the skills to create your own artwork in no time. With that said, two foundational skills could help you hit the ground running. The first is a basic knowledge of drawing to understand certain concepts. If you already know about lines, compositions, values, and shading, you'll be ahead of the game. The second foundational skill is a beginner's understanding of color theory, like how to mix colors or the differences between warm and cool colors. If you already have either of these fundamentals under your belt, you will likely advance in acrylic painting more quickly. But you can always pick up those skills as you go using online tools, resources, and courses.
