Fantasy carriage: I first broke down my reference picture into different parts and noted the perspective. Then, I started blocking out rough shapes to match the reference as closely as possible. After I was satisfied, I added details to those rough shapes. Once I finished modeling, I moved on to UV mapping and finally texturing. To present it, I set up a basic material in UE5 with simple lighting to showcase.
