This looks like reassembly. See iFixit's instructions for this.

I'm not sure what is different between the first two shots, apart from the red rectangle. Use one, or re-shoot so the difference is easier to see.

The series of photos and action shots (showing your hands) gives a clear overview of the initial steps of the repair. Well done! Check iFixit's conventions for markup (your arrow), and notice that the direction it is pointing in is in the opposite direction to the one that your finger seems to be pointing toward. This could be confusing to readers because your finger is more prominent than the red arrow (which is hard to see against the black background of your laptop) so readers are likely to get the impression that the catch should slide in the direction that the finger is pointing in. Could you re-shoot the photo so that the visual information is consistent?

Are you sure you unscrew in a clockwise direction?

Avoid rubbing in a circular motion so that the axis of the lens is not displaced.
