Do you expect the SVG to emulate a hand-drawn picture, become more realistic, or just a more detailed illustration?

As for the often quoted issues with the bike's frame or problem with the steering column, I can't really tell, I am no bike expert.

I can instead judge how poor of a job it is doing with a LOTR rendition in Three.js, so that seems like a better benchmark.

A general benchmark (even Simon mentioned that it was meant as fun at the beginning) should be quick and easy to run, since we can expect that more people will want to try it out. That’s why I’m more like “team Pelican on a Bike”… :) cheers
