Just a bit curious. Currently, mine looks like this. It runs Elementary OS, however considering hijacking it to Bedrock Linux, mainly to get cutting edge software from the AUR (for stuff like Firefox and GIMP) without losing all my data. I think I'll wait for Bedrock to go stable first, though.
It uses the ePapirus icon theme, which is just Papirus with better support for Elementary's UI. GTK theme is (if I remember correctly) Qogir and the Plank theme is the GTK one. What do yours look like?
