Nicht schlecht aber einige Kleinigkeiten sind verbesserungswürdig.
Mach es so:
Hello my name is ____ and I'm 16 years old. I have two brothers whose names are ____ and ____. They're 17 and 15 years old. I also like to go out with friends. Recently, I found out that playing the piano is a great hobby/activity. I also taught myself to play "Für Eliese" by Beethoven. I like all kinds of food, but my absolute favorite is noodles. I have a dream since I was 8 years old of becoming a teacher, but I'm not sure if I'll be able to do so. For my work experience, I plan to do an internship as nurse at an old people's home. I'd like to travel to Japan, and I can even speak a bit of Japanese, although not fluently.
Ich bin zur Hälfte Kanadier, und spreche deswegen recht gut Englisch.
Hoffe das war hilfreich
