Looking cool! I'd suggest checking out some of the runic textures in the machinegames Dimension of the Machine wad. Particularly, they remade some of the classic textures in a larger 128x128 resolution. The metal4_4 bands you have on those giant walls would tile much nicer with the increased texture size.Working on the art for map 4/5 in an episode I'm working on, planning to release all 5 maps at once sometime maybe around september/october
