Pop in D — alternating bass fingerstyle New
Same idea as the basic fingerstyle version on D, A, Bm, G, but with an alternating bass: the thumb switches between two different bass strings instead of staying on one, for a fuller accompaniment ("Travis picking" technique).
Tips
Isolate the thumb's alternation on its own first, without the other fingers, until it becomes automatic.
