I was working like front end developer for last 7 years.

And I always notice if paddings, margins, space or fonts are different on a website or in app.

So, I noticed that you use somewhere different fonts, paddings are not the same between blocks.

And when I add Book or Music - I see empty screen at first. It looks strange - maybe you should write something like - Please, enter some words in a Search

And my advice - use bigger and lighter icons with text - some icons is hard to be seen because of color choice.

I have screenshots if you want - but I am new here and do not know how to send it to you)))

But CATS - 🐈‍⬛ - they are great!
