Oh, andy ash, i like your bed of roses attempt one little pointer i would give like a few other attempts is vibrato technique. Im not critisising (sp) anyone but i think the following may help peoples playing:

To me this is the way to tell a good guitarist. im not sure if you are using your fingers but i find it better to use the wrist, also by using your wrist i find it helps to keep your hand in the right place on the back of the neck. Try to rock your wrist back and forth with a little practice this should give you beter results.

As i said shakey vibrato is not good and im only trying to help.

Andy
