Cool shot! Detail under the vehicle is awesome and I really like the HDR/Topaz effect. IMHO, would have been better for this challenge if the wheel/tire was more prominant in the frame. Maybe if the wheel was turned to the right so that the tire was more in the middle of the frame. Looks like the vehicle may be jacked up so that the wheel could be rotated to simulate vehicle movement (trees are not blurred). Burning of the sky is a little un-natural looking. Overall a great shot.
you are a braver person that I.....HDR under the front of a moving car.....Gutsy move and it paid off....very unique point of view resulting in a great image.
I like the heavy tonemapping here. It's quite appropriate for the subject. My one nitpick is the sky on the right. That grayish tone looks like you may have used some highlight recovery to try and pull in details where there was nothing to pull in.
