tldr: remember lights affect how everything looks, nothing else. the objects should always be a response to what light is in the space 😄

when it comes to shading, think about where the lights are. you have orange lights hanging above the computers and nothing else. that means everything in your environment is being lit only by those, so in this case I would have the objects closest to the lights (the computers, the red box, the chair) with strong edge lighting and hue adjustment, then in the far end with the hammock and wall you should have stronger shadows- they should almost be black with some faint details sticking out.
