At the garden centre there on top of a shop there was a black cat sleeping lazily.
People are busy buying stuff at the markets.
Kids are playing in the fountain to have fun so they don’t get too bored.
People are eating lunch at the bar so are kids.
There’s a lot of trees there.
I really liked the way that you used the word “lazily” to describe the cat. It made an interesting picture in my mind and I could imagine the cat curled up in a comfortable warm spot in the sun, out of the way of the busy people below.
Be careful with the tense in your writing. Your first sentence was in past tense using words such as “was”. In your other sentences, you wrote in present tense, with words like “are”. Switching tenses in your writing can be confusing for the reader.
I wonder what type of things the people are buying? I can see that you are looking very closely at the picture before writing about it.
