Not bad...
You're preaty good, the video quality I guess can't be helped but otherwise you seam preaty good. I'm uncertain about the way the Chaser behaves, you seamed to have tapped the gas a lot going into corners, I dunno why ya do that so I'll just ask why? Is it becuase to maintain control and also keep the engine in the powerband? If that's the case, I would sugest putting a bit more finese with the buttons, mainly the accelerator, try and not jab at it but be a little more smooth...er...it's a bit hard to describe since for me it's natural, just don't press the button all the way sometimes if you want to keep the engine from bouncing off the redline constalty.
Besides that I can't think of much else, you seam to have a good idea on how to drift. Oh yeah, this, I noticed you prob use the D-pad right? Try the analog joystick for more sensitive steering control, take it from a person who's been using analong for just about as long as GT's been around (GT 1 2 and 3...), you seam to do preaty damn good with the D-pad, it may sema a bit odd to go with the joystick but then again that's just me.
The only other thing can can figure is that after the left/right chihcane that leads to the uphill medium right that banks a little...you can keep that skid going so you can shift the weight and start another drift for the left turn there... (I think turn no 7 or 6 reverse...) for a better drift, if I had a video capture card, I could show you with what I did with a Camero Z28 or Corvette Z06 as it was preaty aweesome. Besides that, great job there.
That's about it, till later.
