Race Tracks

Hello Lovely people! I was wondering if someone have any advice on how to make artworks like these.
tutorial/guides/software? Anything that could be helpful
Thanks a lot!!


The one on the bottom is most likely a 3D program. The top one, not sure but probably too (though it looks like it’s overlaid onto a google map in bird’s eye view.)
Maybe Blender would work as a free program to learn on, but… the learning curve is steep.
Can you draw and paint?
