Looks really good! You and I have used some of the same parts, including R2Devo lights, a Vinny shell and a Venky bumper.
I did my own aluminum tubing, though, following Vinny's DIY tutorial and suggested stock from Speedy Metals. Had the welding teacher at the high school let one of his kids TIG weld it together for me.
Where did you get the yellow 'Clippard' tubing? That looks great!
All of my tubing is from GBFans Shop (AJ Quick), as are the resistors, ladder, GB1 ribbon cable, crank knob, gun knobs, acrylic rod, trigger tip, heatsink, and Clippards.
I clipped off the upper solder lug of the small resistor on the ion arm, and now I regret doing that. Wish I'd left it unaltered like yours.
Also on the ion arm, you've got your large Dale resistor with the ribbing vertical. Mine is like that too at the moment, but I was watching the movie the other day and saw it horizontal in several scenes.
I tried to turn it in place but it just locked down really tight right where it was. I'm dreading having to remove the ion arm from the shell to unscrew the nut on the inside so I can rotate it 90 degrees.
Really gorgeous looking pack, can't wait to see it all finished.
