Lam Mud

I discover my singing which have lots of flaws including  phasing problem, some words are flat.
Actually i rarely speak eng. with my friend s and just want to know, u guys can get what I sing???
I have changed few melodies and the mood of the song, is that a bit strange or over??
I dun mind any cristism of my performance, just be curious of western ppl opinions. Thx!!!
