How to create an aura around the player using particles ?

I've tried making a script that would duplicate many particle emitters inside each parts of the player's character (Im using a dummy instead). It works but it's not very "smooth" and some particle disappears because there's sometimes too much particles. If i increase the particle size, the aura doesnt have an "human shape" anymore. I dont know what to do to fix it

Here is my script :

local dummy = game.Workspace.Dummy

for _, child in pairs(dummy:GetChildren()) do
	if child:IsA("MeshPart") or child.Name == "Head" and child.Name ~= "UpperTorso" then
		if string.match(child.Name, "Hand") then
			local particle = dummy.UpperTorso.ParticleEmitter:Clone()
			particle.Parent = child
			particle.Size = NumberSequence.new(0.2, 0.2)
		else
			local particle = dummy.UpperTorso.ParticleEmitter:Clone()
			particle.Parent = child
		end
	end
end

For the particle emitter being copied : Size = 0.3 Rate = 150 Speed = 0Z Offset = -1 (to make the aura to not hide the player) Lifetime = 60 Transparency = 0

Here's a look of what it does : https://imgur.com/a/pMMX3kY (The bottom does have particles, we just cant see it because of too much particles)
