Wow, really a very nice version of the Challenger!!
And I like the overall tone of the set, but there are a few points of improvement (in my opinion)
I like the sky tone in 2. but in 3 and 4 it is too bright for my taste.
And i think the car could use some free space and more of the surrounding in the picture.
I really like the detail shots!!
Just my 0.2$
