Trouble with sprites

[TheMostUpset]

Animation on all sprites plays equally, even if I'm running it at different time. Will be better if I show it on video:

Here is my code:

function EFFECT:Init( data )

	self.Scale = data:GetScale()
	self.Normal = data:GetNormal()
	self.Position = data:GetOrigin()

	local CurrentTime = CurTime()
	self.Duration = 10
	self.KillTime = CurrentTime + self.Duration
end

function EFFECT:Think()
	local TimeLeft = self.KillTime - CurTime()
	if TimeLeft > 0 then 
		return true
	else
		return false	
	end
end

function EFFECT:Render()
if (CLIENT) then
rocketexplosion = Material("sprites/rlboom_1")
render.SetMaterial(rocketexplosion)
render.DrawSprite(self.Position,80,80,Color(255,25  5,255,255))
end
end
