So this is basically me just digging two themes and tried to combine them. I really liked GN-OSC-XFCE-Edition by paulxfce, but wasn't a huge fan of the XFWM4 theme. So I did some searching and found Macbuntu-Nusantara by Etles_Team, which I fell in love with. However, the colour scheme didn't match up so I tried my best to fix it. You can see how it turned out in the screenshots. So I figured, I could share it and save people the hassle if they ever happen to be in my position. So I hope you enjoy!
You have to zoom in on the screenshots to see the difference, otherwise it pretty much looks the same.
I'm aware that the blending isn't 100%, but it works for me. If anyone wants to make improvements, by all means go ahead.
