When I learnt PCB design, you either got a colleague to check your work or you get the PCB back with faults that annoy the crap out of you. With the cost & cycle time that we used to incur it taught you rather quickly to check and recheck. Then I started with a commercial company with deeper pockets, the engineering manager had a mantra of "if you got the PCB back with no errors you spent too much bloody time checking it". He believed there was always going to be something wrong or an unforeseen issue, or an addition of something to make it better, so get your prototype back fast get the bugs etc out of it and then send out a more serious version with most/all bugs ironed out.
Today, cycle times and cost are quite minor so the penalty for a mistake is relatively small. I cant see any drastic issues with the PCB or the schematic. You have a generous number of vias and track side changes that a lot could easily be eliminated but it is probably my old school thinking and of minor consequence.
What I would try to fix is the tracks that do not enter the component pad at right angles. The creation of sharp angles (less than 90) should be avoided if possible. I'm not familiar with EDA but usually when you set up a snap grid of 25mil and use "hotspot" connect, these off centre exits shouldn't occur ? I was always taught to not use 90 degree changes of direction when running tracks, and use slanting lines (like you have in some areas) again probably old school thinking.
Other than that it looks good to go.
