Here, I will write in English. Let it be a challenge to you :) So, this is what I have to say about your playing: your hands work by and large properly. Maybe a little work on string changes in the right hand would be in order, so they are smoother and quieter. It's not a huge problem, just something to pay attention to. It also appears you have absolute pitch. I just had a long conversation with your mother about the pitfalls of having absolute pitch (I have it myself), and what you can do to counteract them. So if she starts giving you dictations to be written in transposition, you can blame me for that :P And I have saved the best for last: your tone, expression and facility are fantastic. I would like to see you move a little more freely with the music, let it carry you away a bit. Given the current state of your playing, I think you can permit yourself to do this. I know you are still relatively young. To your credit, you do not mention your age here. I think that is a good thing, as it will place the focus on you as an artist. I think you have a good future ahead of you, and I wish you all the best :)
