You got some interesting stuff going on in that Alfa set, I like shot 2 the softness and cold feel suits the location, good atmosphere in it.
Shot 3 has a nice tight fight feel and energy and the warm toning on this one works too.
Shot 5 is also nice the same soft feel but the atmosphere come across well.
And the last is very nice indeed. The sense of speed is great, the coposition is nice and the isolation of the red car on green surroundings works very well.
Good work 👍
As for your latest set, your entry shot is nice and one of the best in that set, my only crit on it though is whether it best relates to the theme because it's hard to se what colour the car actually is and considering the theme was about a specific colour it may have been better to show the colour off more. Still its a nice shot. 👍
Shot 5 also has something that draws me in, which is good. 👍
