Yeah its a fun site, glad you like it. The oscillator looks much better now. 

A few other things about the layout, your concern for trace width is unessesary, an SX pin can only conduct 25 mA safely, a 1 inch 8 mil width trace can carry 1/2 amp and only raise in temperature 1 C. The only traces you should have wide is the power traces. 

And if your layout software can make flood filled areas you should make the entire back flood filled ground (it will route around your signal traces). 

Pin #1 should come off parallel, not at an angle, the odd layout you have can create electrical "echo chambers", it is so short that its resonancy is probably in the gigahertz but its better to be safe. 

If you reroute the trace going to the top pin of the oscillator so that it loops under and around the second pin your need for more than two layers disappears.

On your I/O lines try to avoid 90 degree turns, this can create reflections in the signal. And make the trace to the upper pin of the oscillator so that it doesn't have a 90 degree turn, if you can't manage to fit it in, move the oscillator to the left just enough to permit it.
