I had the pleasure of meeting up with fellow Korean teacher "Your Korean Saem." She's a specialist in Korean pronunciation and intonation, and she shared with me her advice for how to improve.
It can take months or years for learners to sound more like a native Korean, but that doesn't mean it won't happen. My pronunciation started out quite bad in the beginning (I still remember how I sounded) and only through time and practice and a lot of immersion was I able to improve my own Korean to sound more like a native speaker.
Nowadays you don't have to stay in the dark - there are tons of resources for helping you to improve the way you sound. One of my favorites is "Your Korean Saem," a Korean who explains pronunciation in an easy to understand way.
