To be clear: as a prototype, it's more than fine. As long as the UI isn't the innovation, make it real first and experiment with it as much as you can. Show it to users, see whether they understand it and see the value. As a domain expert, making your ideas real in any way will make it easier to bring others on board who can create a pleasant experience. The UI you're showing now looks more like a bag of controls thrown on a page by a backend engineer in 2006 and less like a B2C product in 2026. Various boxes all over the place, weird colors, misalignment, inconsistent spacing, confusing what does what, a random calculator(?) in the middle of the screen, unclear abbreviated labels. It needs so much work that a full rethink might be in order.
