im no good with color cuz i render in monochrome but you can definitely use more contrast, also rim lights and all that jazz
look up some tutorials on lighting, shadows etc. itll help make shit look more professional
i fucked around with it for 10 minutes and did a very shitty job trying to explain what im talking about so i recommend you to actually look up someone who knows his shit about color and lighting but i hope it helps illustrate my point
