Fingerpicking

I have recently been trying my hand at harder fingerpicking songs such as rhiannon by fleetwood mac, and slowly but surely the easier songs are getting easier. I am know able to easily play the introduction to Landslide by Fleetwood mac, I have even taken some simple fingerpicking patterns and added them to some interesting chords making a little tune. Bar chords are still as hard as ever, I am able to play them if I slow down but I am currently unable to quickly switch between them. In general though I am improving a lot.
