My wife has a book set on a planet with frozen methane lakes which necessitates the use of battle mechs, heh. I love MechWarrior’s Timber Wolf so that’s what I included in the prompt but I didn’t give it a reference image.

Sadly, while they all look good, all lack the Timber Wolf’s trademark shoulder weapons and conical cockpit.

So I gave it a reference image

But oddly, the output looked even less like a Timber Wolf. And the output approximated the drawing/shading style of the reference image.
