Interesting subject in the first. I suspect it would work quite well as a BW or sepia toned image as well. My curiosity wants to see the image as presented. But the action is around the tines and, from that point if view I might crop around the exposed piston on the left.
Second doesnt mean enough to me to really know how to comment. Seems like it works best as you have presented it, as part of a series, providing more context. Only thing I can suggest is to crop a bit more off the bottom, since the OOF area is relatively large and distracting. Maybe leave just a trace. You still have those nice track lines coming into or from the lower right corner.
What kind of race?
