Very cool. 5-fold symmetry on the PCB to use up the board allowance is particularly neat.
A trick that poor hobbyists learn early on is to make pads a little larger than necessary for SMT parts so you've got somewhere to wick solder onto. Neopixels (5050 LEDs) are reasonable to hand-solder since the pads extend up the sides of the package, but you can also do QFNs with a bit of practice by placing a big via to get to the central pad from underneath.

Cool! Remarkably similar to Voria Labs who produce a product called Lumanoi https://voria.com/
Perhaps an example of convergent evolution? :)
