Hey everyone! Iām new to VFX and this is my first particle created with UE4ās Niagara, I have experience in some animation and materials and would love some critique on where this one could improve with it 
Youtube Link ā For HQ and more angles!
Welcome to the forum! Nice start in Niagara, I really need to start learning that . . . 
One suggestion might be more size and shape variation in the ice projectiles and impacts; I can see they are different when I focus on them, but the initial impression is they look/feel fairly uniform so making pronounced variations could help with quicker readability.
Nice work, have fun learning Niagara!
