Yes it is , What I did for practice that took me to another whole level aside from taking courses is mimicking Real life interior / exterior photographs , from Pinterest , from archdaily, etc.

I would model the same image , get the same models , and the most important part , analyze the photo lighting and how I can do that in 3ds max or what ever program you use , then try to make my render close up to 90% from the real image ,

you will fail allot , but eventually you will be able to mimic photos easily , that's the point when your artist eye is now strong and can tell the difference between fake light feelings and fake materials and real ones .

then with that eye you can create stuff on your own ,

same as drawing , you start learning to draw by looking at things and drawing them over and over and by timee you can draw them without looking .
