Cool Design :-) Maby one can reduce powerconsumption while put a resistor between the base of npn and ground :-)

You can also remove the p-channel mosfet and tie the gate output to base of npn via 1kohm, decreases current draw while on and simplifies circuitry

Also, if you're going to power such a light load, you could use the collector of the NPN to pull your bulb to ground instead of burning extra energy to switch the relay on

I love seeing this kind of thing. pseudo 3-wire, using gates so you can use a single pb is awesome
