Hi Bogdan, I assume that you are looking for people to say, "I would do it this way or that way" I will be the first to say something: You play very well. Something that I would do a little differently is, in the cadenza, I would take my time a little more. There are times where you could leave some space. Let them wait a little for your beautiful playing. A cadenza is a personal thing and you get the freedom to do what you want so, maybe you are doing what you want. When I write, I use a lot of punctuation. Maybe, I overdo it with the commas but, I do it in my playing too. Just a thought, If I can help a player as good as you, I feel honored.
