Tank looks good.
Ditto with everyone on the hose clamps. Yeah, the mailorder ones are a rip-off, but I'd rather not save $2 and end up with far more expensive problems.
Opinion, take or leave it:
Angels are known to be problematic, can nip and often do so more with age. Yes, some people [almost always with quite large tanks] can get away with it ... but that's not the average IMO.
And even with an upgrade to a 120, that's IMO still too small a tank for long-term housing of them at full size. We are talking about having this fish for a decade or more ...
I think one of the Tang articles in Reefkeeping recently quoted some growth figures for one family, and a remarkable % of total growth happened in the first year. Like with any small animal - the initial period of it's life is crucial for proper development and growth. Don't know if Angels are exactly the same, but it leads you to think they might.
IMO, unless you have the tank bought, I wouldn't buy a fish that will outgrow your current one.
This is a great hobby, but life always takes precedence when the car needs something, the house needs something, your health needs something ... and your upgrade just might have to be put off, rightly so. Don't paint yourself in a corner, IMO ... esp after complaining about the price of lighting. A bigger tank's lighting is even more expensive
Anyway, that's my take on it. Tank looks good as is.
I wouldn't stock with fish/bioload very heavily until your corals are in, growing, and the tank is doing great. Bioload can be tricky to manage in my experience, and it's hard to know which fish will be `one too many'.
[large fish = large increase in bioload, IME larger bioload = harder to avoid algae problems, algae problems = tank looks mediocre and is a lot of work]
IMO, get the tank thriving, then add the final `feature' fish. I've consistently found corals a lot easier to grow with less fish in the tank ... my opinion says build the tank so that it's next year's Tank of the Month, and realize that it probably should take the whole year to get stocked to that final point.
Once stocked, it should give you happiness for a decade or more ... build it up slow.
