Great stuff 👍
The first one in post #305 is very cool. I love the almost HDR-ish blue sky tone, it really gives a great impact on the picture itself. I would advise you to be more careful with the blur levels. The car is a little too blurred. A more sharped car would have more impact on the picture 👍
The corvettes picture has really great colours, a bit over sharpened and some minor "cleaning" issues, but, don't feel rushed to go overboard and clean everything.
The last one is great, the composition and the blur background vs. the sharp car is perfect, though, and as Nenad said, the car is a bit too bright in relation to the background. But, it is great anyway 👍
