Great job! Since you are listing more than one hobby, you have to make it plural (hobbies) and you have to change the linking verb from "is" to "are", since that is for plural nouns.

A means one so you can't say a pictures. I changed take to taking and practice to practicing because the ing form of the verb can mean the act of taking or of practicing. In English we use the ing form of the verb instead of the infinitive like you would in Spanish sacar fotos or practicar inglés
