I'm practicing Serbian out loud, but how do I know if I'm butchering the pitch accent?

I've been recording myself reading news articles from RTS to improve my prosody, but I find it impossible to hear if I'm actually hitting the rising/falling tones correctly. I feel like my sentence intonation sounds 'flat' compared to native speakers, and I don't know how to bridge that gap. Does anyone have a systematic way to self-correct these pitch accent issues, or is this the point where I should look for a human ear on Chickytutor.com to verify my recordings and give me specific feedback on my vowel duration?
