chuck-  visualizing the chords helps to identify pitch collection and leading your melody thru the changes.  keep trying it.

peter-  there is a slight release in your left hand.  don't let the chords ring.  don't dampin w/your strumming hand! it's more of an even strum.

charles-  practice using a metronome on all beats and  2&4.  try using a flecking motion.  keep in mind good guitarmanship.  play along with basie records/cds.  pk

hey peter-  you're welcome.  thank you.
