Pronunciation and accent on my songs !

Hello everyone, I'm not a native speaker but singing in english is my all time absolute goal, I'm really concerned about sounding good.

I need your opinion and advices, am I understable ? Does it sounds odd ?

Here's one of my song, I'm the one who starts to sing, the second singer is Australian.

Thanks a lot.
