Hello everyone! I'm designing a PCB and I have some doubts about how to connect the 4 resistors at the top to capacitor C34. They are 4 traces, and all of them terminate at the same pad of the capacitor. As I have currently placed them, are they connected correctly? Or should I connect them in a different way?

Why not just connect all the resistors together with one straight trace, and put on trace between that and the cap. They'll save copper and make the board cheaper.

Would they really? I made only one PCB so far, but there your price was independent of design. I also don't think they save a significant amount of copper either way. Would they notice at all? When you etch away the copper from your PCB you would need to measure how much copper your etchant took in and I would imagine that's not worth the effort. Feel free to correct me if I'm wrong though.

I know of no PCB fab house that prices production on how much copper is etched out of the foil (even though they recycle the dissolved copper afterwards). On the contrary, i usually got the advice of leaving as much copper on the board as I could, as it makes their life easier (and balancing becomes very easy).
