Looking great, man! You could also shorten up that hose to the brake booster, that's something we did on our supra just to get it off the firewall.
I do think you could go with a little less flat black though. If you're going for the non-flashy look it's cool, it just seems like a lot. Perhaps go with a theme, like the car is white, so go with flat black and white. Or maybe even some gold/white combo with the black would look good. I just see a bunch of different stuff. Red, gold, blue, flat black, gloss black, silver, yellow.
I can certainly appreciate how much work goes into a tuck, having done it before, and you are doing a fantastic job! Keep it up!
