I also thought it'd be fun to show the setup I used, so here it is!
My phone goes on the grey plate between the white bars to stay stable and the green plate is attached so it doesn't move. I rotated it (and removed the needed walls) for the different sequences.
And this is what I used to get a closeup of the plant. My phone went on top of the white structure so it could stay stable between the shots.
This was mostly for practicing my editing skills, namely for sound effects
I also built a setup which connects both a plate for minifigures to walk on and my phone to stand still, allowing for more fluid shots
As for the editing, I did what I could using the BBC sound effects (which is free to use, and rather easy to navigate), but there is for sure room for improvement
