It appears to me that you've swapped the 3n9 and 390p capacitors at C5 and C13. See labeled PCB diagram below. Based upon their locations in the circuit, I think this is the cause of your problems. Fix this mix-up and see where you're at.
I'd also straighten out the alignment of the charge pump (IC3) in its socket, while you're at it. Otherwise, the quality of the build looks excellent, particularly your wiring.
