I can see a problem with the fuse circuit. It will blow the leds if the fuse opens. The green led will also have reverse breakdown with the fuse closed.
Below is another way to do it.
Placing the diodes in series with their respective leds, instead of across for reverse protection will reduce the power dissipation in the resistors by 50% and is most probably a better idea.
The 2 diodes were placed in series in the original circuit to make the voltage drop higher to cause the green led (with a lower on-voltage) to be on during normal operation.
You could also use a neon & resistor over the fuse. Putting another cap over the neon can make it flash if the fuse opens.
