Very good updates, Luke. The Skyline shots look pretty good, although, as Luis has already said, the blur in the second shot is too soft and glowing. Nonetheless, the idea behind the Skyline set is amazing and I like every single picture of this set. Then there's that beautiful Viper with those fantastic rims. I like the chaos in the background, too. It gives some special touch to the whole shot. The BMW shot is good, but you should'vr removed that line which goes over the driver's door and the rear bumper of the car. The car would look much smoother and better, in my opinion. 👍
Then there's the RUF... First of all, you've done a great job on cleaning it. Although there's still some places to be cleaned, the car looks pretty good. The lighting is great, too.
