Maybe it's the car I'm not really liking - looks like a lot of Z28s I see. Anyway, the last post is better - I like the brick building and the sky. The other cars distract, imo, by disrupting the Camaro's roofline/curves. Also, there's another car or something behind the hoodline. I'd try shooting from a different angle on the Camaro, consider rule of thirds, and keep the background uncluttered but use the brick building and sky. Maybe try to work the sky into the car somehow, cliche as that might be.
