I would personally like to see the egis become more detailed. I don't mind them being small and whatnot, but would it be too much to ask for something more similar to the original? Just a little bit?

Like maybe give ifrit-egi scales and a mouth?
Make titan-egi look more solid and darker? It honestly does not look very sturdy :P
Maybe change garuda-egis pose and add feathers instead of wind effect?

I don't know, just... something to give them more "oomph"?
