My only comment is that your resistor values are too high all around. This could lead to noise and offset issues.
I would use 10K for the dividers, and about 22K input impedance (R1/R4 and R2, respectively), and 22K/1K for feedback loop (R5 and R3). Capacitor values of C1 and C2 will need revising to roughly 10x-20x their listed values to prevent LF cutoff.
About the PCB, some tracks seem longer than they need to be - the one connecting C3 and R2, for instance, can be routed much shorter, and it's a pretty critical connection to minimise noise as it's a low-level signal. I would also not use a ground plane. Even if it's dedicated to low-level signal circuitry, the way you've done. A track is better to control where the currents are flowing. I would return R3 halfway between the input and power grounds, on the other side of the plane instead of the edge. This may require a little more tinkering. It will work just fine probably, but tweaking it slightly will help your S/N ratio.
I would also look at a way to get a small film cap in || with the output cap. Actually, I would prefer you use a split supply as that eliminates the output cap and the R1/R4/C3 circus. However, that's your call.
