Hi Emanuil,I am not familiar with the pieces you played except perhaps the 2nd piece of the 1st clip, but I liked the way and the flow of your playing. I hope the teachers in this forum will give their inputs soon. Thanks for posting.BTW regarding your question about equipment used in our videos: We use a high definition cAMERA, a Cannon, but there are now better performing and cheaper Panasonics. The audio in video cams, even the good ones leave much to be desired, so I use the ZOOM4HN audio recorder using the 4 channel mode. The extra 2 channels utilize Shure condenser microphones and placed about a foot away from a fully open lid. I hope I have answered your question.
