Same here, first week in and like mentioned, certain cords not clean and that fat finger feeling. Like many have said and instructors, you can adapt and overcome.
I too have been paying attention to Lisa's finger positions, even though mine dont bend that way..... yet! One thing I am thinking is that over time when your finger tips get tougher they wont squish down so far on the strings making it cleaner, at least thats my hope.
