By the way, I think you should add vias near GND pins of the driver chips (assuming the bottom is ground). Otherwise the return current has to take a round trip around the whole bunch.
the top is ground, the bottom is VCC, and I have a void in the middle on both sides where the high speed traces run, someone suggested it.
I made this to learn anyhow, so if it has problems that's not a failure
I'm relying on the small size (the drivers are SC70) to keep the return paths relatively short, plus I kept extra margin on the sides of the board so the plane has more surface area.
