It's interesting to study video games because you can choose the composition and gets a sense of the scene from different angles.
The downside is the crazy perspective from the virtual camera and the lighting conditions are not realistic in most cases. I still think it's good practice. The next step is probably to take multiple screenshots of the environment then draw it in a new composition or take an existing composition and draw my own design in its place.
Of course all for practice.
