Looks awesome!
One suggestion for you - by the looks of your template markings, the layout of the pickup cavities and the electronics cavity appear to be extremely close in proximity...there's not much margin for error between where the bottom of the pickup route meets the top of the electronics route. So, you could potentially drill through the top and have a hole open up in the bottom of the route where the cavity is.
I'd aim for a minimum of at LEAST a quarter inch of space, preferably more - between the cavity route line and the pickup route line just to give you a little wiggle room in case of any slight variations in deviation from center line.
