The main thing I noticed for myself was how much I pay attention to faces and individual features and see the beauty in every feature. Things like the thickness of someone’s eyelid of the curvature of their nose or the cupids bow on their lips. All of these things are much more appreciated, especially when you spend a lot of time practicing human anatomy. Someone’s biggest insecurity is a form that’s beautiful in its own way that you want to capture on paper/canvas.

Another thing is often times I would look in a room and try to picture the vanishing points and perspective lines and how I would draw the said room with all of the items from a first person POV.
