Hi, when I work with my students, I always suggest that they should practice technics, such as scales, im, mi, ma, AM ami,ect. Scales on 3string, 6 strings, two octave scale, 3 octave. Chromatic scales of 4,5, or 8 notes and to do that whit understanding .To relax the RH. Abel Carlevaro book for RH, such a great book ect.
After all that you should input your techic and your ideas and ability of techic in to the piece that you working on. There must no write or wrong fingering,
