Looks good for an initial effort, my main criticisms are:
- far too much pilot volume, its probably similar to your chamber volume!
- a cheap slide valve or three way valve could have replaced both trigger and chamber refill ball valves, and made the design much more efficient and quicker to operate.

I could have gone with a three way valve but I was being cheap as usual and just went for two ball valves.
As regards to the pilot volume I couldn't really think of a configuration where I could reduce it, the space between the joints and tee could of been reduced but I wouldn't be able to fit my hand comfortably round the trigger.

... you could have attached the pilot ball valve directly to the QEV, then fitted an extension lever to the handle to act as a trigger.Alster370 wrote: but I wouldn't be able to fit my hand comfortably round the trigger.

I just realised when testing for leaks that I can use the pressure release on my pump as a pilot for my gun. It works very effectively, and instead of dumping all of the spare compressed air it only takes a quarter or so of the pressure away. So instead of refilling the secondary chamber , im only topping up the air which is stored in it. So could i say I have effectively reduced pilot volume by 75% in theory right?
On a sadder note, when testing the airgun with 0.12bb at 40psi , one bounced off several objects resulting in it making a very small but annoying crack on my lovely 23" acer monitor.
