Okay, I looked at your website. I see your main pitch is the “analog” thing. You should edit the first post of this thread and the thread title to reflect that.
Some thoughts:
Film editing
Scrub smoothly with precise control through your edit.
Music production
Produce different sounds based on the speed and/or depth of a key press. Similar to playing the piano and pressing a key string hard or soft.
Super secure passwords
Everybody has their own unique typing behavior and input methods. The keyboard can trace this unique typing identity and recognize it’s you filling in the correct password.
For scrubbing through film, a jog wheel (or mouse scroll wheel, or trackball, or similar) is much better than an analog button.
No offense, but the super secure password thing is really dumb. Existing passwords are already hard enough, making the password need a particular typing style is going to just lock people out of their computers.
For musical instruments, analog keys are great, but not in a QWERTY/ANSI keyboard arrangement. If you want to make a musical instrument, you should make some differently shaped keyboard, designed for the purpose.
There are definitely plenty of other cool possibilities with analog switches though. Will all the switches be analog, or only WASD + spacebar? What is the mechanism? Magnets? Capsense? Optical?
I suspect your biggest problem will be the software chicken-and-egg barrier. That is, right now, nobody has analog keyboards, so there’s no reason for software to support it. Because there’s no software support, there’s no reason for hardware vendors to build analog keyboards. USB HID is going to be mostly useless for fully taking advantage of analog keys, so you’ll need some kind of custom protocol support on both ends, which is going to take a ton of work to get working across platforms. All the best luck though! I’d love to have more analog computer inputs out there in the world.

Are your renders showing the actual shape of your keycaps? If so, you have too little space between keys, and the keycaps overall are too flat and uniform, in my opinion. It’s easier to press keys accurately when there’s adequate gap between keytops, and adequate step between the home row and further rows. Standard keycap tops are larger than ideal, and were designed mostly to fit several printed legends on them, because some international keyboard layouts need up to 4 symbols printed on the top of the key. The smaller “spherical” keytops from keyboards made in the 1970s were better, as far as touch typing is concerned.
For analysis, see
http://johnbear.net/symbolics-keyboard-paper/MacIvoryKeyboard.pdfYour layout right now looks roughly like an Apple chiclet laptop keyboard, with deeper key travel. The Apple laptop board’s keytops are larger than they ideally should be, but it’s not the end of the world because they have such low travel. If you have a full-travel switch with similarly tight spacing, typists are going to end up making lots of mistakes with their fingers hitting two keys at once. The flat, unsculpted keycaps of laptop keyboards are a necessary compromise to keep them thin. If you have a normal-sized external keyboard, there’s no reason to make that compromise.

Edit: Many, many modern keyboards get this wrong. The standard cheap backlight-friendly “OEM profile” keycaps used on “gamer” keyboards are all quite poorly designed.
Sorry if my rant about keycap shapes sounds too negative. If it seems like an off-topic distraction for this thread, and you’re stuck with some existing keycap shape, I can edit my post to chop it out.
