How could I put my avatar into a viewportframe?

So I’ve been trying for a while to recreate this effect, made by tze.

effect by tze:

what I have so far:

all I really need is for my avatar to appear in front of the clones, and for it to not turn green from the colorcorrection. I think it is possible with viewports but I have very little experience with them

tldr; I need to see my avatar through a viewportframe constantly
