Way to go! I overplayed when I started out and had such sore fingers that I had to use everything inluding sensitive toothpaste on them (not fun!) Very smart of you to shorten the practice time. It is such a good feeling when you start to play "real stuff". Keep it up, it will just keep getting better from here on out. :)
