I'm relatively new to fingerstyle - I've played Nothing Else Matters, I got the feel for fingerstyle, however in that song i didn't use any other fingers than my thumb and my first finger; I haven't got much experience in using all the fingers (excluding fourth).
I'm learning a new fingerstyle song currently and it includes using all fingers.
From what I know, thumb plucks E, A, and D strings, first finger plucks the G, second finger plucks the B, and third finger plucks the high E.
But, I'm developing slightly bit different finger-string pattern.
What's different in my plucking is, i pluck both the D and G strings with my first finger, instead of my thumb on the D. It feels more natural to me.
So i was wondering, should i kind of force myself to stick to the usual finger-string pattern; If i keep to my own pattern will it create problems in future?
