Watch the ii I V/7 vi V iii ii Etude Level 3 online guitar lesson by Vicki Genfan from Open Tuning Handbook: Rhythm
See how you need to move your thumb around for that Em11 in the 14th fret. I would suggest practicing one chord change at a time...super slowly. Some changes won't need much work, others may take more time. Eventually you'll be able to string them all together without pausing in between chords. Again, play around with these chords in different order and see if you can find some new progression you like!
