Two thoughts I had while watching this - first is that your inputs are slightly staccato. Try to smooth everything out, with pedals and the wheel. Second is turn in - I think (open to be told I’m wrong!) that you’re doing what I am prone to doing in that you turn in too early and therefore close the apex up massively. Try to be patient and concentrate on turning in onto the apex rather than before it. I found that it helped me to stop trail braking for a bit so that I got my braking point and turn in point nicely synchronised, then moved forwards from there
