I like the texture of the metal and the reflection in the window. The crop does not feel right for me -- I want to see either less or more of what's shown.
Nice old truck. unfortunately your composition does not do it justice.
I like the idea you had, showing the garage sign, a shallower DOF would have blurred the sign more and would have highlighted the truck.
I wish you would have waited for the shadow to cover the entire truck, not just parts of it - causing the high contrast areas. If you look at the words Chevrolet in front, you see how beautifully the blue sky shows up in the shady part and how washed out the left part is. The reflections of the clauds/sky in the windshield also take away from your picture. Just a person opinion, but I would not have cut the light in half.
All of this is just my thinking and my ideas. Showing the beauty of cars is not easy. Usually it's done by unusual/low angles and from the side.
Great 'old' shot and the garage sign compliments the image completely. Baeitiful red and blues. perhaps it could have been a fractional amount sharper on the grill but still a good 7
