Do master studies of Studio Ghibli’s backgrounds or scenes! Copying masters is a great way to learn, and it doesn’t mean the rest of your work has to be 100% like theirs. But it allows you to really understand what makes the art you like and then you can use elements of that style in your own work. You could make a list of elements to study if copying an entire painting is too much. If a painting is overwhelming for me I break it into a line drawing (focusing on shapes), a value study, and a color study.
