Very nice and beautiful reveal to start with and I love the music. However, I would trim off a few seconds of the part that starts with a static view of the castle, after which you climb and move forward and then tilt the camera down, to look down over the top of the castle.
That few seconds of standing still messes up the rest of the very well done flying and filming. You can take up the extra time with the music by increasing the black fade in point.
One more point, since everything else is slow and smooth I would change the way, you brought in your title and simply keep it still but fade it in and then fade it out to black, without that flying in method you chose. It will be a much nicer effect, especially with the music fading in with the title. And since I'm at it, I would suggest changing the font to something more classic and timeless. That would much better suit your classic and timeless castle.
