I enjoyed these two. I think you might well consider doing more improvisation and composition and less playing classical. The trills don't matter; rough technique gives rise to many more ideas than does smoothness, which is an overrated playing tradition. Neither does it matter at your age if you sound like somebody else, I didn't find my own voice until I was fifty-five. Aside from this, if you develop the creative aspects, they will reward you immensely much later in life.
