Describe someone
I would like to talk about my little brother. When I was just a little girl and he was born, I have to admit that I was a little bit jealous, because all the attention was focused on him. Even when he was just a little boy, he tried to protect me and take care of me, and I took care of him as well. Now he is 13, and he is one of my most beloved ones. Sometimes he can make me nervous, but deep inside me I love him very much, I can tell him all my problems and opinions, and he tries to hel me, and so do I, I only want the best for him. Sometimes we fight and we have arguments as well, but we love each other very much, I'm sure of it.

Dear Mª José, this is a wonderful description. It has helped me to know really how your brother is. The structure is good, but if I were you, I would make a stronger topic sentence because your text would show off ever more than it does. The supporting sentences are great because they're made me understand the text without difficulties. You have also given a lot of reasons that show you love the person you are describing, your brother.
The vocabulary is great, you have avoided repeating the words and you've used synonims.
The concluding sentence is the best part of the text, because the length is perfect and it doesn't add new information, but sumarizes the whole text with just a sentence.
In a few words, your writing is wonderful, and it's difficult to improve it. If soon noticed that you're very fond of writing and you normally do it in your daily life.
