Item rejected, how can i further improve so it get accepted?

I have created android template app, the idea of it is that it has already built-in bottom navigation view that behaves like instagram, not at all like the regular android bottom navigation view, also using a ready to go mvvm architecture and other technologies, anyway it’s a template that you can take and fit your needs if you are willing to use bottom navigation view in your app, but it got rejected as “unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again.”, and the reviewer said “With more unique features, I’d definitely be happy to take another look at this.” so while looking at screenshots below, how can i improve?

(Note: screens(layouts) are just for declaring the idea in how app works, user will change screens to fit it to their needs)
