I'd like to describe picture number three. in the picture we can see a girl playing the piano. The girl is in her teens. she's got long straight dark hair. she's wearing a blue blouse and light blue jeans.
she's sitting on the chair in front of the piano. she's in Music classroom, I suppose. there is a green plant on the piano. there is a bookcase with lots of books next to the girl. The girl is looking at her hands and the piano-keys. She is trying to do her best. I like this picture because it reminds me about my music classes. In my childhood I learnt to play the guitar.
