Default Changes in layout

Error in schematic for the DC offset decoupling led to rework in layout. Board size is now 72.5x50mm.
Description:
*5V external voltage regulator
*DC offset circuit
*Ferrite bead linking analog and power ground
*SMD capacitor footprints designed for Rubycon MU or ST / Cornell FCA / Panasonic ECPU(A), Vishay PHP 1W SMD resistor at output filter, NXP PMEG4010ETR,115 clamping diodes.

Again any advice regarding layout/groundplane/component selection would be appreciated.
