I like this, but you should definitely redo the shade of yellow. Maybe try something based on the Engineer's hardhats, and maybe make the blu version orange? That'd be pretty cool as a team-colored one.

"Hey hey hey, come on over to have some fun with craazy taxy!"

like many other war paints I've seen on the workshop, the pattern is good, but you just gotta fix the angle the paint displays itself at. patch it up and it's a good win to me.

i feel like the stripes should have been aymetrical like on a real taxi.

It's not really yellow though, it's a yellow-green.
