I believe your issue was actually the fact that you were using a Quikrete concrete while the video appears to be using cement. They don't seem to differentiate, and how they expect people to know the difference, I don't know, but it's clear by the fact that what they're using remains a flowing liquid that resembles the wash basin at the local DIY pottery shop.
The concrete aggregate stuff contains sand and other particles way too large (even after sifting), so it won't form layers: it's designed to settle and interlock for strength. Cement is the actual base component of concrete: a much finer powder, a mixture of gypsum, clay, anhydrites, some other stuff, and limestone powder.
If you buy it in the store (Home Depot carries it in tubs of Quikrete Fast-set Cement or just bulk bags of Quikrete Portland cement will work if you're patient), you will immediately notice the difference: it's a very fine dusty powder.
I got faith man, Mrs Brown will have her eggs!
This adage was drilled in my head growing up: "If you can't whistle to it, it ain't music and if you can't chin up on it, it ain't strong enough." That being said I actually liked the exterior application better, it left opportunity for sculptural creativity. The whole thing looked too weak to me. So I was thinking, pour a first coat with exactly what you were using, that way the interior will be smooth. Then using rubber gloved hands apply a coat of Quickwall fiberglass reinforced concrete and then a third coat of what you have used. You could leave part of the ballon exposed so each layer could be feathered. Quickwall was developed for making dry stacked walls in mines I have been told. It is incredibly strong. I have used it for outside sculptures and used white cement to hide the fibers. It isn't necessary, depends on your aesthetic.
