It was beautiful.
Your animation principles were a little off, the astronauts were a bit too tween-like (robotic in movement) and lacked some squash and stretch. However, the style was one of the best I've ever seen here on Newgrounds. Not only that, but it's very refreshing to see a movie on the main page that is being celebrated for truly being quality, as oppossed to just sick humor or popular. Congratulations, you truly deserve all this praise. Excellent message.
