Take a photo, use a mosaic / tile filter, then recreate image as pixel art and animate from there. I also like gradually reducing image sizes in sequence to break them down to more or less pixelized versions which can help make it less overwhelming.
Maybe fireworks would be a better example than flowers, shading the clouds above & below. :)
I'm old school, started with MS Paint back in 94, everything was pretty much pixel art. animated gifs were all the rage. Good luck with your projects! Hit me up anytime!
