Flame from Embergen, exported it to Open VDB and importing it into Blender. I had to use an experimental build of Blender 2.83 to be able to import Open VDB. The step size wasn't as high as I would normally use for a smoke simulation but that was fine since I was just making an image and could manually paint over it in Photoshop. Both software I used in this instance were beta builds so there were some hiccups along the way. At the end though I thought I came out with a decent result.
Rendered in Blender and Enhanced in Photoshop. I'm finding that this is a great workflow for Vis Dev/ Concept art. I am doing a Daily Render during the weekdays for the duration of this quarantine. The rules are that they must be done that day, no backlogging.
