Hi,
Please see this as a help, not a criticism. ok. [pcb-errors]
Please check your board in details and try to see what i meant with this so many of the blue rings.
First: T-routing must be switched off.
Second: arrange all parts on the board in this kind that you get functional groups with very short wire length, rotate the parts where ever you can and also see your cosmetic stile as well; why not - a nice board makes happy.
Then….
The best way is if you route this small number of wires via hand because you learn with how to route well. (route instead of autotroute).
First the shortest then the longer then the power wires.
Bypass caps must be placed as closer as you can to the active device in that rotation you don't need route around its pins.
This is also for all other devices so good as you can as well.
The better way is if you don't route between the pins also not surround that pins.
If you can, meaning if the plugs, jacks can be rotated then do this because this saves wire lengths.
In other hand if not (this is the normally restriction), if this devices must be so fixed on that places, then place the connected parts so that reduce crossovers during routing, meanly save numbers of vias.
Try to route vertical an horizonal, 45deg over long distances should be the exception. - Functional groups helps it to get short wire distances.
Keep more distances to the devices and the between the wires as well. - electrical calculation must be involved.
Also for the power wires and distances to the connectors.
Make the wire thickness by seeing the signal current, power current, voltages, frequencies (eg. clock signals are very RF happy and have very a strong distortion, sinus signals are "warm" signals -> EMC), and so on....
So, hopefully that helps a bit.
This was a fine job, congratulation, and now we make a rearrangement, an optimization.
Good luck!
Best Regards
Gerald
