Introduction okay?

Hi, my name is Sven. I'm 36 years old. I'm from Germany and I living live near to Frankfurt Main. I'm here to improve my English skills , especially my speaking skills, and perhaps to learn other languages too  as well.

The official name for Frankfurt is Frankfurt am Main(Frankfurt on the Main river), right? No one needs the official title; Frankfurt is referred to as Frankfurt alone by the rest of the world.
Note the use of commas as parentheses(brackets).

Being precise and compendious goes a long way towards achieving fluency. :)
Good luck!
