Mostly what
Tempo said. Great angels, sync, music choices.
Its really nothing I have seen before. Nice shader, transition use of characters and shaders. The replays were nice. Its amazing that OLDA is producing really amazing videos and competitions lately.
After the beginning of the 'Lady Killer' song, it was funny, less serious, even more laidback. The length of this video is great. Some say 'OmG long video im nawt watchin dis. I'll get bored'. This video kept me tranced into the video, unlike just a bunch of replays.
Who ever said too much of a good thing is bad? This video really is amaszing. Nothing I( and most[all] of the community) have seen before.
Goodjob deady :'D
