"A Pillar of Fire by night" study & an untitled study

I'm settling into my new studio, and am welcoming some fresh approaches to my painting practice.

Here are the beginnings of my investigation into representing the Pillar of Fire by night. I've been using Golden interference paint mixed with a thin polymer to play with luminosity. 90x90cm.

An old piece of semi-oil primed canvas has led to this. Dark acrylic paint has soaked into the edges, as well as tinting the oil prime. Gold interference paint on top. Clouds? 30x45cm.
