I agree with don firth, that it is not all in the right hand. I find with finger picking and particuarly melody picking the left hand is very important, pulloffs, hammer ons, slides, bends,use of additional bass notes based on the pentatonic major scale[ which are executed withthe left hand]. a common mistake that beginners make is to assume that there is only one position for a chord, lets say D major,and not find other inversions .not to work out where modal chords are as awellas minor chords.finally I ADVISE YOU TO MAKE A DIAGRAM OF THE GUITAR FINGERBOARD.and learn where all the individual notes are and where they are repeated in different positions.And then to get some basic music theory, so that you understand the difference between major, modal, minor, chords and why they are different.
