I noticed this some time ago while I was drawing fan art, and I believe it's a natural issue to happen. 3D is more difficult than 2D because there are so many aspects and details to consider. However, if 3D is executed well, it can offer a much better gaming experience for sure.
I’d say that visualizing stuff is an interesting part of your work if you enjoy it. It does take time, though, but think of it as a refreshing break from your usual tasks.
And yeah, the holidays are just around the corner! I don’t have any big plans, but it’s the kind of break from work I’ve been wishing for over the past few months. :D
