How to write his or her really good composition?

My uncle is an expert in painting. He wears a pair of beautiful glasses, with a medium build and a small nose. With big eyes. My uncle studied painting in Hangzhou Art School and won the first prize in the school competition.

One day in the summer vacation, I went to my uncle's house. I just walked to my uncle's door and found that his door was covered. I knocked on the door three times Nobody answered, so I went in. My uncle is absorbed in painting. I walked behind him gently and saw my uncle draw a waterfall and a lotus flower. Waterfalls seem to be flowing, and lotus flowers are like lotus lights. It's really lifelike. I can't help applauding. My uncle's paintings are great!

At this moment, my uncle turned around, looked at me in surprise and asked, "Yi Ming, when did you come?" I replied, "I have seen you draw waterfalls and lotus flowers?" After I answered, I asked, "Uncle, how can your painting be so good!" "My uncle didn't answer. He took out a dozen pieces of thick paper from the cupboard, and the pictures on each piece of paper were very similar. I asked my uncle, "Uncle, did you draw all these pictures?" My uncle replied, "yes, people often say,' many things grind'." "

I went to my uncle's room, and the wall was covered with awards, including the first prize in primary school, the first prize in middle school, and the most striking one was the second prize in the national competition. I can't help saying, "He's really good!"
