My first note: My introduction

Hi! I'm Rina from Japan. I'm not good at speaking English, but I want to (I would like to) speak English in order to travel to abroad. So, everyone, please teach me (English)to me!! Of course, I'm good at speaking Japanese! And maybe I can teach Japanese to you. I'm looking forward to talk to everyone.
I'm in 2nd grade at university. I live in Hyogo, which is near Osaka. Do you know Osaka? It will be fun to speak about Japan and about your country. I want to know about many countries.

Well, do you think this sentence is too short or wrong? I'm waiting for your comment or advice. I'm very excited. See you.

wanne = informal colloquial English, used especially by American English. Some would consider it as "slang"

correction

better way of saying it
