This is so much different from your first one...which was more like a landscape. Here you have a really great close cropped look to this pickup truck.
Your proportions are good, and you did a fine job on the foreshortening. You did a really good job of capturing the lines and character of the 1949 to 1953 Chevy pickup truck.
You have a greater range of values here than in your first one. And good i love the textures and surfaces of this truck.
It's a great piece of work!
