It's nice! It reminds me a lot of the metallic puzzles Heiowge makes. I saw your video on it as well, pretty cool puzzle.
Some constructive criticism: when I saw the video, the amounts of glitter on the edges of the puzzle are sort of uneven, some of the edges had a lot while others had not as much. But eh, it's just aesthetic. A small price to pay for a great puzzle! Nice job!--JC--
