Flickering LED 5

I'm trying to make a simulated flame lamp using parallel sets of single flickering LEDs in series with two regular LEDs. To make the flame ignite and extinguish slowly, the output of the PIR sensor (simulated here with a switch from a 2.6 V supply) is used to fill a capacitor and trigger a Darlington arrangement of transistors. To avoid the lag when turning on, the capacitor is kept charged at about 1.3 V via the potential divider across the 6 V supply. Whist this works well for just one set of LEDs, the simulation says that multiple in parallel will be dim.
