This image is a still from my last animation which you can find here:
Everything what you see in the video was made with Blender. I used After Effects only for some postproduction, mostly in the last shot. Everything else is pure blender (particles too) + some grading in AAE.
I'm not very advanced Blender user and I did some things in my own way. Like the very first shot where you see hot metal. I used animated texture to create displacement because I was unable to get good results with Blender's noise since it hasn't any evolution parameter which I could animate.I hope you like it.
