I think you did a nice job with this study. The tempo was well-chosen, the playing was clean and the tone was full and clear. I liked the way you ended the piece very much.
I agree with Matt that just a bit more dynamic level variation and, perhaps, a slight bit of rubato--consistent with Sor's classical style-- would add some more interest to the piece.
