D_P, you really have a good eye for very dramatic angles! I'll go through each picture:
Trueno - That track is hard to get good shots off, so that's an accomplishment right there. The angle makes for a really good sense of speed, but the road is a bit blurry. The colour and cleanup are both great, though!
R32 - I already said it in the comp thread, but be careful with noise. It can detract from an otherwise great shot

.
NSX - This is an aesthetic thing, but I feel like the wheels are too small, and/or the ride height is too much. Something needs to be done about that... but I love the colour tone of the shot, so I'm on the fence overall.
Jag - If there were a shot that should start GT4 up, that's it. The feelings, the nostalgia, the lone car beating around the track. Just awesome, and proof that simple isn't always bad 👍
RS6 - Those wheels look absolutely incredible! It's too bad it looks like the car just hit lightspeed

.
Focus - Very clever angle, the car's speeding... off the side of a boat? Well, nobody can tell, and it works, in this case. The reflections are nice, there's a nice feel to the shot, and while the A-pillar and surrounding area seem a bit out of focus, it's a minor nit-pick. Overall, very well done!
Aston - I wish people would be more adventerous like this with their angles. It totally heightens the sense of riding the edge of traction, and the less intense colours work very well for this shot. The relationship with the back half of the car and the dirt behind it seems odd, but I can't place my finger on why. Not that it matters too much; this shot is far and away the most dramatic 👍
SST - Now that's the right amount of noise. The geometry of the shot works, drawing the eye through the picture, and the truck stands out very well because of the colour. Also, it's driving towards the sun, a brighter spot on the image, again forcing the eyes along a path. Very well done, that tiny bit of glow (or am I imagining it?) is just icing on the cake
