Create a cinematic, highly detailed digital painting of a Lunarpunk robot sitting on a Charging Construction in an action pose, inspired by Nicomachus of Thebes and goth transformers. The scene should be set in a dark, stone- walled environment with power energy emanating from the construction. Incorporate a beautiful, stray- like picture in the background and use a gradient blue- black color scheme with spotlight effects. The composition should adhere to the golden ratio and feature intricate, lifelike details. The overall style should be reminiscent of the works of Artgerm and Greg Rutkowski, with a mix of elegant and brute elements
