Please indent like this:

  (package
    (inherit breeze-icons)
    (name …)
    …)

> +           (synopsis "Artwork, styles and assets for the Breeze visual 
> style")

Please write full sentences for the description:

Is it GPL-version-2-only?  That’d mean that source file headers (or
similar) explicitly omit the “or any later version” wording.

In general, use of ‘@’ must be avoided: it’s better to just import the
modules you need.

More importantly though, you must not inherit from a package defined in
another module as that would prevent modules from being loaded.

The solution here is probably to duplicate all the fields instead of
inheriting.  In this case, that’s probably not going to be much longer
anyway.  And if you want, you can add a comment saying that breeze is
based on MATE or something.

HTH!

Thank you,
Ludo’.
