Hello there,

Here is the result of the build process:

I think the icons look pretty good. However, I would suggest removing the "original" version from the font attribute since it's very similar to the "plain" version. There's no need to add an alias for the "original" either, you can just remove it.

Everything looks good. Good job 👍
