I'd recommend 'The Tale of Despereaux' for beginners. The castle in the story has an architecture that can be easily grasped. The dungeons, the hallways, and the chambers are described in a way that is beginner - friendly. 'James and the Giant Peach' also has the architecture of the giant peach itself which is fun and not difficult to imagine. And 'Charlie and the Chocolate Factory' with its fantastical factory architecture that is both exciting and simple enough for beginners to get into.

First, you need to learn about the fundamentals of drawing, such as perspective and anatomy. Also, look at a lot of comics to get inspiration. Another important thing is to start with simple concepts and gradually increase the complexity as you gain skills.
Start with basic shapes and simple lines. Practice sketching characters from different angles. Also, study anatomy to make your drawings more realistic.
Beginners can try practicing different expressions. For example, a big smile or a surprised look. Also, using light and shadow can add depth to the caricature.
