Not getting what I want

Hi All,

     I'm trying to generate an image of a throne made of fire and smoke only - no solid chair, just the smoke and fire in the form of a throne.  I keep getting images like this -

My prompt was - throne made only of smoke and fire and light, hyper realistic

It's a cool image, but it's not what I'm looking for.  Not sure what else to try.  I have tried dozens of variations on that prompt.

Thanks,

BG
