Hi Manu, from our observations of your vibrato.. the issues were not really related to pitch. The pitch was good. The point Darius was making was that by having an irregular approach to vibrato (sometimes doing upwards vibrato on the G string, for example) could lead to pitch issues. But overall your pitch control is very good.
It was purely the physical approach we were looking at.
Here your vibrato sounds great but I can still see you doing upwards vibrato on the G string. You do manage to make it work somehow but generally we don't do this as it's not as comfortable or easy to control. I've added some detailed stuff in the REC take.
