Very good.

Here's a tip that helps make MPGs smaller:

Don't use checker as the pigment for your plane, at least not in the
final rendering.  My first IRTC entry was much smaller (and looked
less like a newby effort) when I replaced the checker pattern with
a granite pattern.

If need be, you can have an if-else-end block to switch between test
renders (because the checker pattern is quite useful for eyeballing
measurements).

Regards,
John
