R14 and R15 are 100KΩ? Seems to me that would starve the devices for current. I missed it too. You would be better putting a emitter follower to use as a voltage regulator similar to what I did, and dropping the resistor values. As is, you can only get 0.1ma through that, and it gets worse when loaded.
Look at a functional diagram of a 555, you'll note it has 3 5KΩ resistors in series internally, not counting the rest of the circuitry. The CMOS 555 will be much more efficient though, but you're also trying to light LEDs (10ma) with that too.
