Trying to mimic what you hear on the radio is a great way to develop your ear. Nothing at all wrong with that....

I have really small hands also, and it does make some chords harder for me to get. I'm more of a single note player, just kind of turned out that way b/c I had the same problem with the hands. Small hands make it harder to fret some chords. I bought a 7 string a few years ago and eventually sold it b/c the neck was too wide for me.

My whole point is to not let the small hands keep you from playing the guitar. It never stopped me.....
