First off I have to say the focus is, obviously, spot on. You have chosen a very good working depth of field. The composition really struck me though. It isnt overly complicated. Its nice and tight but has so many little dynamics to it. From the texture of the smoke cloud on the left, the dappled sunlight on the car and ground, the timing which caught the flying dirt to the right and the angle / tilt of the camera to give it just a hint of uniquity. Often you find photographers trying to "force" a skewed angle onto a composition and more often then not it doesnt work but you have skillfully pulled it off. I really have to commend you on your choice of moment and where to aim your camera. That dappled light literally makes the shot. It makes the car pop and gives the smoke, and whole picture, a real 3rd dimension. As well you are tasteful with your post work. Often with car photography, among other categories, you find photographers who become horribly over zealous in Photoshop and you sir are not one of them. It is quite obvious your level of artistry and professionalism is easily in the top percentile. I think you did an overall amazing job and as with most of your work I am envious.
