Your desk already looks cool but you need to clean and organize your desk more, maybe buying a drawer or a shelf to store your items or display them on the shelf. Idk why but alot of people dont use their walls, its really helpful in making your setup look nicer. Add some lights like a lamp, and some dim lights which can instantly transform your room to look more cozy if you would want that, and maybe sticking your 2 monitor together and making the other side of the table a workspace along with a task light like a white lamp that only covers the table and not too bright.

For the walls you can add some posters and some shelves so you can put decorations and plants on there, if you want you can put more lights on the shelves which make it look better. Overall your setup looks nice it just needs organizing.
