I think it's really good work.   Just feedback since you asked for it.  I like the main center one with the big truck but I don't too much like the "eyes" aspect of it.  It looks too much like a crayfish.   It kind of takes the focus off the truck.  There is just a little too much feathering and it obscures the main focus of the truck.  I like when the trails kind of form horns like a bull near the bottom (bull market).  Otherwise, I love the power of it.
