1. d00d u do have a good voice.
2. nice strumming of chords
3. But the high pitch parts needs to be worked on.
4. + one thing: metronome - sometimes due to strumming or singing we tend to get faster / slower than the beat of the song. metronome helps keep in the beat. The metronome's sound wont come in the recording.
5. Nice reverb u've added. Not overdone it. Good.
