[help]i want to change apperance of maxwell's shadow

[neemo]

Can I change the appearance of the shadows summoned by Maxwell?

In my character's lua file 
inst:AddTag("magician")
inst:AddTag("reader")
inst:AddTag("shadowmagic") 
inst:AddTag("dappereffects")

I succeeded in implementing it properly by adding the above code.

But the Maxwell-shaped shadow doesn't suit my character.

What syntax should I add to my character lua file?

And on which route 
Is there a file that can change the appearance of the shadow?

thanks for comments!
