Cute pastel rainbow colourway with adorable novelties.
It's great to see photos of the full set sample ahead of time. Especially when it's a newer dyesub PBT manufacturer that the community is unfamiliar with. Are there other sets they have made?
The keycap wall thickness will have some detractors, so perhaps a sound test may help? (Although who knows how much to trust sound test videos).
Is there an estimate for the all-in-one base kit cost?
Seems like you're forcing novelty designs for the enters, arrow keys (including accents), and tsangan bottom row modifiers which is a bold decision. Is there a total key limit restriction for the packaging or pricing target limit?
There's no basic 40s compatibility which some users would be annoyed about, nor cover for other spacebars, but I presume the target market for this set, is more for the casual consumer that goes for cute sets and keyboards in the beginner/budget range. The geekhack community which skews towards more unique layouts isn't the target demo here.
Maybe one day you can do a more uniform profile with centred legends?
I do think the Enter novelty key should spell 'UNICORN' and not 'UNICON'. I know it's probably a deliberate decision due to the constraints of the keycap size and the scale you want the letters to be at, but do try to find an alternative solution, as it looks a bit odd.
Either a different novelty, or adjust the kerning/scale to fit the R in there too.
