Simply BreathTaking.
The only shortcoming I felt too, is Sektor's flame.
It's a bit lackluster, needs more aggression, realistic curves/flickering.
Looks a little cheap and undetailed, a blob of jello lava,
like a plastic spring-loaded projectile ready to be shot out when you squeeze his legs.
(Makes it overall seemingly a giant action figure, rather than a high end statue.
)
Perhaps begin with a straight line of fire coming out, gradually forming into a deadly upwards puff?
Doesn't have to be huge. Cyrax's blades look sharp, Sektor's fire needs to be just as deadly.
