Dude! I think you nailed it! The addition of Tink and the fireworks is great.
I think I prefer the gold, but the silver looks good as well.
I get 1971 as the year that WDW opened, but I don't think I see "2025" anywhere?
Or is there the potential to do an inscription around the outside perimeter of the coin? On the edge itself, not on the obverse or reverse? You could put the year there and maybe some other text. Just a thought.
