Inb4 any comments about this, I know playing acoustic isn't really different from electric but what I mean by this is correct technique for fingerpicking etc...

I've searched around and saw that people seem to recommend books by Frederick Noad and Aaron Shearer for classical guitar technique, but before I buy one of these I was wondering if there were better alternatives either in the form of a book or online lessons. I can't afford lessons in real life before someone suggests that.

Tl;dr - Moderately experienced electric guitarist wanting to learn correct technique for fingerpicking right hand and general "acoustic" technique, suggestions?
Get a teacher. With a book you'll never realise your own bad habits that a book may not focus on. Even a few lessons with a teacher is better than a book.
