IMO it looks too much like a mobile game UI
The elements are really large and take up a lot of the screen with poor information density.
I’ve linked call of duty’s UI as well, it has a similar issue.
The BB ui is a good example of how to do things right, the menu on the right is dense and quick to navigate on mouse. The BB components themselves are also mostly dense, they just have a lot of inputs/labels, but the size fits the function.
I’ve linked the SE block ui as well, as you can see it’s far denser in its fitting of blocks so it’s much more comfortable to navigate and visually appealing.
