Hola, Ignacio.  Tu vocabulario es muy bueno, pero fue unos errores de gramaticas. 

Hi im new and i wanna talk english

Hi im ignacio flores im 20 and im from chile
i wanna talk with foreign people of my age to practice mi way to speak
im a little bit good writing and i wanna talk
im searching for a friend of my age to talk in skype about games.. maybe a movie or of the life haha
just wanna have a normal conversation and learn in the try and maybe i would try to teach to my friend my language if he/she wanna learn.

It would go a bit more like this:

Hi, I'm new and I want to speak English.

Hi, I'm Ignacio Flores, I'm 20 and I'm from Chile.

I want to talk with foreigners that are my age to practice my speech.

I'm a little bit good at writing but I want to talk.

I'm searching for a friend my age to talk over skype about games... maybe movies, or life haha.  I just want to have a normal conversation and learn in trying, and maybe I would try to teach my friend my own language if he/she wanted to learn.

That's all.  Bye.
