I will say that I think the design and look you're going for would lend itself much better to a softer, less sharp POM. Aluminum might look a bit too sharp and not really "cheesy" and the coloring, whether it's anno, cerakote, etc., rather than just using a yellow POM is gonna look a bit off.
Also in the google form, you might want to change the options to allow multiple selections or a ranked list (e.g I want a stepped caps option + a regular shift and backspace, I like a POM plate but a PC plate would also be nice if there's enough interest, etc.)
That being said, this is also both hilarious and creative and I really fw it, looking forward to seeing a POM proto
Although I preferred the rendered look more at first, the prototype colour is growing on me and definitely has a more legit 'Swiss cheese' look to it.
Yeah the renders are a bit more eye-catching but also not accurate to 'swiss cheese'. They're more the colour of cheddar and maasdam.
The prototype yellow being less saturated is closer to Swiss cheese, but from the photos, it's still a bit off and I think there's room for it to be even nicer and more accurate to Swiss cheese.
It's not the end of the world whichever route Bregoli takes, but I'd suggest taking it to the next level; renaming the project the Cheeseboard, and offering 2 or 3 colour variants; because cheese can be almost white, pale yellow and saturated yellow in colours.
Yeah I would say for this, the best route is to ditch realism and go for a more cartoon-y look, which would include that more bright yellow/orange color of the renders
