PCB Layout Critique/Thoughts/Etc...

Just for kicks, I'd like to gather opinions on how I like to lay out my PCBs. Here's an example shot (the labels point to the pad directly inline above or below the label):



A couple of things...

1. I like to put my LED resistor onto the board and run the LED neg back as a trace to jump to the switch. This usually means I have to run a trace around the entire perimeter if I can't work it back under components.

2. I like to put my switch, jack, and power traces on the bottom of the board (closest to those parts) to avoid running wire over the top of the board.

3. I try and run the traces to where they're as close to the contacts as possible, thus my board in and out are right inline with the switch lugs, -9v on the left, jack in an and out on extremes, etc.

I know doing this adds a lot of extra distance on some of the traces, but I haven't noticed any ill effects from doing this. That said, what are some reasons I shouldn't do PCBs like this -- assuming there are some?

Thanks for the input!

I dont see any problems with what you have here.

Some thoughts:
Keep all high impedance traces (inputs and connections from output stages to input stages down the line) as short as possible for noise pick up reasons.
