Thanks a lot for your descriptions. They are ok, but there are several mistakes you should change. Now, I’m going to introduce myself following the example given in class:
Hello! I am Cristóbal Ángel. I am 25 years old. I am middle-aged. I am handsome. I am tall and fat. My face is round. My eyes are small and brown. I have got short and blond hair. I have got a small nose and my ears are small too. My lips are thin and I wear glasses.
