RE: It's ready for maiden, however.......
Good luck on the maiden!
I may be talking out my *****, so others should chime in if need be and correct me... I see a slight potential problem, the pipe mount tabs have just one screw on each tab.
I think it would be wise to add a second screw to each as this would stop any side play that may happen gradually over time and cause a hot spot in the pipe.Up and down play on the pipe should be non existent as well.
One tail shot (first pic) looks good as far as pipe & engine alignment, but the second *appears* to have the engine askew a touch by way of looking at the tailcone/turbine wheel vanes.
BTW, the jet looks fabulous![8D]
