This is old pixel art I did in Game Maker Studio 2; effectively I wanted to make this cyber kind of wall tile, very detailed, subtle, and very well constructed with making a distinct aesthetic style that would blatantly show it's my style.

Back then I did more style in order to show how I create pixel art versus others; in truth I used a lot of reference art of 3D models and translated it to 2D pixel art of 64 by 64, I don't have the exact image but one idea that stuck out to me was from Tales of Xilla 2 where the generic wall sprite happened to be. I decided to take that, and put my own spin on it, making this more like pipes instead of straight line wires, to give a feel of pumping something through the walls.
