Well, i enjoyed this FX sync, its well made but however try to not overuse same effects.
If you really love FX like i did
use more CC's than this "single" effects and for slow motions use TWIXTOR because this help alot.
Use better replays at least try to not use this ammount of Multiplayer replays because it looks weir and i dont see nothing special in it.
Song its not bad chosen, however i will try something another. Also is VERY VEEEEEEEERYYY important to sync the replays! If you will sync only the FX's like you did its going to be really weird and sometimes will even looks even shitty.
You should ask in events section for replays, this will help alot. But i like some parts.
