Introducing myself

Hello! My name is Elena. I'm nineteen years old, althought people usually think I am younger. I'm from a city of Seville, which is called the city of the eleven towers. I am a student of nursery in Seville. I am a short and thin girl. I have a long, straight and brown hair. My eyes are small and brown. I usually wear casual clothes, jeans and t-shirts. I live with my mother, my father, my sister and my dog. It is called Lucky. It's adorable!! In my free time, I love listening to the music, reading books, painting, playing the guitar and going out with my friends!! If I could, I would travell around the world. I love learning new languages and making new friends.

I am a student of nursery in Seville.

I'm not sure exactly what you mean here. You could mean 'nursing'  or 'nursery'.

Si estás estudiando para ser enfermera (nurse) entonces puedes decir 'I am studying nursing.' En mi opinión esto es lo que quisiste decir, pero pudiera ser equivocado. 

Nursery = guardería. El significado es un poco diferente de 'nursing'. 'A nursery' es un lugar en el que la gente cuida a los niños.

Un saludo.

*here, some people put a comma, although some don't. This is called the Oxford comma, which you can look up for yourself. Most people in the United States put a comma there, while every other country (Canada, UK, Australia, etc.) most people don't.
