I don`t see a need for such a simple circuit like this. More important thing is ground laying, which in this case is done as it should be.
Some recommendations: Diodes D1-D8 should be TO 220 case diodes of your choose. I have a larger quantity of NXP (Philips) BYW29E-200 too. R1&R2 could be either short circuit or MPC71 0.22 ohm. Optional snubber circuit (R3-C5; R4-C6) consist of 1 ohm resistor MPC71 and 100 nF MKT cap.
