Slow cars?

It took me longer to paint the cars than anything else. I did them mostly in negative space. And when it came to painting the houses behind the wall, I had lost my energy. Don't ask me what colours I used. I'm trying to empty some old palettes. There was a yellow, and orange and two blues. But that's as much as I can say!Again, all done in direct watercolour. No drawing beforehand.

 

And here's a version in which I've added gouache in Procreate. I'm not sure why the colours look different.
