Dust Disintegration Effect Recreation (Avengers Infinity War)

This is my attempt to recreate Avengers Infinity War Avengers Infinity War dust disintegration scene. This was created using Maya, After Effect and Red giant plugin.
The goal is to put myself into a scene and blend myself to fit the scene with color grading.

*All the scene rights belong to Marvel's Avengers Infinity War, I just use this for education purpose*
