Oh Birkin, it's you, one of my favorite photographers! Hope you didn't mind my comment below. I'm sure I just didn't understand your idea properly, because you are about a zillion times better at this than I am.
I think this might be more effective (for my taste) to go out a little to get the entire objects in the frame, or alternatively, in much closer to get just the wheels or some other small but identifying part. The glare on the car and the small bit of road in the background is kind of distracting. You met the challenge topic and did well with the sharpness and the colors, though.
Very effective use of the angles and nice way to show that the basics behind the idea (wheels, carriage) are still the same though the details have progressed considerably.
