BlenderOS 4.2 mobile phone animation



I followed this YouTube tutorial put together by huge menace to construct a cell phone with their extension called ND. I of course I added some of my own touches to it.

Is there anything I can do to make a better?

I posted the animation to my phone on my Instagram page at https://www.instagram.com/p/C-tHFTBC9ha/?hl=en
