So, there is something called "mural painting". It's a type of art where people paint really big pictures on walls or buildings or other big things like that.
And there are some special places called "institutes" where people can go to learn how to make these big paintings. It's kinda like going to school for art but you only learn how to make these big pictures.
At the institute, they teach you all kinds of things like how to pick the colors you want to use, how to mix them together to make different colors, and how to use different brushes and tools to make the painting look good.
They also teach you how to plan out your painting, like figuring out what you want to paint and how big you want it to be. And they help you make sure you stay safe while you're painting way up high on a big wall!
So, if you want to learn how to make big, beautiful art like that, you can go to an institute of mural painting and they'll teach you!
