Icon Fixes

before: The face is a bit long and the hair was to wide.
after: still have to much of a black space under the face.
 after after: I made the face even smaller to show longer hair, and took
out the half circle or forehead section. I made the framing more specific to
the white shape being made. 

before: the sections of the fingers were looking like worms..
after: I even those out and and made more space between the nails and finger
so that they are not lost when icon is scaled down.

before: the black strings were uneven and were creating a grey
when scaled down.
after: now when the guitar is scaled down each string is still seen.
