Yeah you need to connect the two parts, it would look a lot better.
This animation is really sick but as you did with part one, you rushed the ending. The explosion effect at the end looked awful, it completely lacked dynamic movement and the blood rain was extremely short. I understand how animating in pivot gets very boring but with such an awesome animation and buildup the momentum of the animation falters.
Hope this helps still a fucking awesome animation, I kinda want to make a wu vs ob animation now
