Practice makes perfect~ that is a standard cliche but it is so true so if i were you~ try to find multiple language partners and try to have sessions with them. Make sure it is regular..as some of them, surprisingly, would oblige themselves to help you. I am an English teacher and I can teach you accents as well so :) Let me know if you can swing by online. :)

Hi Marsi, you can always improve your English. Just learn to navigate around this Italki site. Click onto all the programs on the top of the page, do the exercises, then go up to find a language partner & email one of the native speakers to arrange a time on skype or msn. Your other option to to get a private English tutor who lives near you. I hope you have a lot of success with your English studies.
