nice enough...
some possible tips:
use a tripod - wobbly hand held camera in 1st video
frame what you are filming better - there's a lot of dead screen in the first video
edit video to remove silence at end (maybe not all but in the second video there was quite a lot) or use more delay/reverb tails
use modulation sources/vcas/etc etc so you don't film your hands and/or film something else
don't do free advertising for racists/misogynists etc

the first 3 I think are pretty important, the rest are just taste and/or ethics - and obviously don't really count if you are demoing stuff - but then I'd like voice-over too - here I'm adjusting the XYZ knob to do ABC to the sound etc

Utility modules are the dull polish that makes the shiny modules actually shine!!!

sound sources < sound modifiers < modulation sources < utilities
