Glowy Two-Tone Material Effect?

I have this skeletal mesh that is a low poly hawk that has 2 simple flying animations. I want the hawk to glow gold and second tone color. How could I create this material based on these really cool abstract art that I found which is exactly what I was imagining what I want my hawk material to be like? Would it be better if it was done in Niagara particles?

This is what I got so far in materials for the bird.

Have you seen this? I think it’s relevant here:
