You can do this easily!

The sample prepared is a new canvas (illustration) of the expression color "color" of 800x600px

 

then, let's begin

Create a "black to white gradient layer" with sub tool gradient

I accidentally made the sample from black to transparent

It's okay if you leave paper (white)

next

Select "Gradient map" of the new color correction layer from the menu layer

Select “Sunset” from the sky in the gradient set.

Then, slightly adjust the gradation knob (as shown)

A gradient map layer is created on top of the gradient layer

next

Create a "new raster layer" between the gradient layer and the gradient map layer

Set the composition mode to "Overlay"

From the menu filter, select “Draw” and “Perlin Noise”

I set the scale to 50 to match the canvas

Please adjust the flame size by checking the preview

Done

later

Place a character or burn wood to create an atmosphere

I think it's good that it looks simple but it looks amazing
