Thank you!! It didn’t actually take too long to make the GTK theme, as that was just basically a recolouring of the Materia theme with some very basic modifications. It was coded with scss, so it was basically a matter of replacing the variables and regenerating the theme.

I used oomox for the icons, the only thing that really took some time was the vim theme, which I basically made from scratch. As of now, I still need to add more language-specific highlighting.
