Figured I’d start sharing some of my shots.
To get the ball rolling, I’ll start with this one.
While my favourite from your first two shots is the first one, I feel the shot would of turned out better with the aperture set between 8-15. While using a manual focus so the left quarter of the car is in focus. As well as a few areas near the front of the car.
^+1, looking forward to your next update.
+2 here. Nice shots so far, just keep experimenting. With the first shot, I think it would’ve been even better if the right of the car wasn’t cut out of the shot 
Using Focus and Aperture will really give shots a leg up. The thing after that to learn is framing.
For instance l think that last shot of the barn and Ford would be completely transformed if the angle had been dropped a little, camera brought closer to the car so that the trees, barn and the car would fill most of the shot and you’d have a decent amount of aperture with the rear of the car in focus. Now the trees get cut and there is a lot of uninteresting dirt in the shot.
All the things l’ve mentioned here are things l had to learn myself when l just recently started from zero.
Nice angle in the first shot!
Cool action shot!
