Don't think so. R4 limits the Q1 base current to a safe value., although I think 10K is too large and could prevent Q1 saturation. 2.2K probably is a better value for that.The resistors R4 and R5 at the output of the opamp with the capacitor C1 will delay the light transients at the input of the light sensor.
This delay will reduce the shatter of the relays.
