Hm, good attempt. Singing wise, it was alright. Guitar playing needs some improvement.
To start off, your guitar is out of tune. Tune. and I think you havn't been playing the right chords.
The tune starts off with 079900 069900 and 009900. transitions in the the chorus which use the same chords. then when it get to " i'm thinking of your vague reply " it should be C#m --> 009900. and then it transitions back to the chorus.
The little guitar part played during the transition part from the chorus to the bridge is :
e---------------------------| 4x
B---------------------------|
G---------------------------|
D--14-14-14-13-13-------|
A--------------------14----|
E-----------------------12-|
Hope that helps. Nice try
