The 3D art that you have on your website is really cool, I like the old theme. You could definiley turn that into something backrooms-like and make it creepy.
i tried to redesign the doom section of my site, i don't like how it looks or how it's organized, but i'm not very happy with the attempts i made to redesign it either
i used the ibm vga 8x16 font from here: https://int10h.org/oldschool-pc-fonts/fontlist/font?ibm_vga_8x16
