I follow SpaceX developments quite closely and this animation is fairly on the target as far as the current understanding of the entire stack goes. Keep in mind that SpaceX is building Starship in the open and the entire test and assembly site is filmed 24/7 by enthusiast from numerous vantage points, allowing them to learn quite a bit about how it'll all come together. Another important thing to keep in mind is that the booster and the ship stacked makes this the tallest rocket ever at 395 feet tall (120 m), even taller than Saturn V. It's 9 meters in diameter. This thing is gi-gan-tic and it's being caught mid-air! Amazing job by C-bass for the quality animation.
