You just want opinion correct?

I think you would have to provide a lot more information on what it is, what’s unique about it, what your goals for it are, who the target user is etc.

Like, maybe your ideal user doesn’t care whether it looks unique? Or maybe the fact that it looks familiar is exactly why they go with it?

Or perhaps making or modifying a design system is something you actually really want to learn about personally? Or you see that as the only reason why someone would choose your app?

Personally - I would try acquiring the first user/s by focusing as much as possible only on what it actually does, ie. productivity. Then I would try to base those kinds of decisions on what they actually tell you. And on what you see them doing with it.
