If you're collecting pictures of keyhole lips, save a front view and a side view of the same mouth. One angle on its own doesn't tell an injector much.
From the front you see the small parting in the middle. From the side you see whether the fullness around it pushes forward or stays close to the face. People use the same name for both.
Bring both and say which part you actually like. The conversation goes a lot faster than pointing at one screenshot.
I keep a guide to the keyhole lip shape with the sources side by side. It helps you describe a look; it doesn't plan a treatment.
