Let's talk about details.

I'm trying to learn how to draw things more quickly, by taking advantage of basic shapes, and simplistic lines that do not copy each detail like a camera, but instead create the illusion of detail.If I draw a bird, I can't take the time to draw each individual feather exactly as it is. How do I still create the illusion of all those feathers and their complexity without taking away from the drawing?

I'm taking peter Hans course, and I understand what he says, but I feel like I need more examples on how to simplify things to understand it better. He made this palm tree very quickly, and it looks nice. He was able to recreate the detail, but did it with simple lines and patterns instead of copying it perfectly.

Are there any more examples like this that I can observe? Or maybe someone can tell me about how they do it?
